Definitions
- the present disclosure relates to power distribution devices, and more specially, to low-voltage power distribution devices.
- low-voltage power distribution devices also known as low-voltage power distribution accessory products
- leakage protectors such as leakage protectors, arc fault protectors and overvoltage/undervoltage protectors etc.
- Some low-voltage power distribution devices can provide one or more of the above functions.
- Conventional low-voltage power distribution device has a closed state and an open state. In the closed state, the low-voltage power distribution device connects the main power supply to the load circuit; in the open state, the low-voltage power distribution device disconnects the main power supply from the load circuit.
- the low-voltage power distribution device generally is provided with a control circuit board which can control a tripping mechanism to trip in case of faults like leakage, arc and overvoltage/undervoltage, such that the low-voltage power distribution device is switched from the open state to the closed state, thereby preventing the above faults from damaging the power supply or the load.
- the low-voltage power distribution device usually adopts a connection approach of an upper incoming line, i.e., an incoming line connecting the main power supply is connected from an upper interface of the low-voltage power distribution device while a lower interface of the low-voltage power distribution device is connected to the load circuit. Accordingly, in case of the above fault in the circuit or the low-voltage power distribution device, the low-voltage power distribution device cutting off the power supply of the control circuit board while triggering the tripping.
- a variety of low-voltage power distribution devices employing the connection approach of the lower incoming line are also developed to satisfy various needs of the uses, for example, the users are forced to connect the main power supply to the load circuit via the lower incoming line due to different reasons.
- the lower incoming line means that the main power supply is connected to the lower interface of the low-voltage power distribution device, and the load circuit is connected to the upper interface.
- the interior circuits of the low-voltage power distribution device are not adjusted correspondingly, different problems occur when the low-voltage power distribution device adopts the connection approach of the lower incoming line.
- EP 2 455 961 A1 discloses a method and a device in accordance with the preamble of claims 1 and 4.
- An aspect of the present disclosure is a method according to claim 1.
- the tripping condition comprises at least one of overvoltage, undervoltage, short circuit, leakage, and arc fault.
- the method further comprises in response to the tripping condition being met, providing an alert signal to users.
- a second aspect of the present disclosure is a low-voltage power distribution device according to claim 4.
- connection assembly comprises a first conductive contact coupled to the detection unit, a second conductive contact coupled to the power supply, and a conductive member comprising a first contact portion and a second contact portion, the first contact portion coupled to the first conductive contact, the second contact portion adapted to contact the second conductive contact in the closed state to communicate the detection unit with the power supply.
- the low-voltage power distribution device further comprises a handle capable of switching between a closed position and an open position in response to an user's operation, thereby switching the low-voltage power distribution device between the closed state and the open state; and a driving member pivotally provided in the low-voltage power distribution device, and operable to rotate from a first position to a second position in response to the handle switching from the open position to the closed position, so that the second contact portion contacts the second conductive contact.
- the conductive member further comprises a third contact portion
- the low-voltage power distribution device further comprises a test assembly
- the test assembly comprising: a test unit used to test a validity of low-voltage power distribution device; a test contact coupled to the test unit; and a test button adapted to drive the third contact portion to contact the test contact in response to a press of a user, thereby communicating the test unit with the power supply in a case of the second contact portion contacting the second conductive contact.
- the first conductive contact, the second conductive contact and the test contact are conductive pins provided respectively at different positions in the low-voltage power distribution device.
- the conductive member is a torsion spring
- the first contact portion is a spiral portion of the torsion spring
- the second contact portion is a first free end extending from the spiral portion of the torsion spring
- the third contact portion is a second free end extending from the spiral portion of the torsion spring.
- the term “include” and its various variations may be understood as open-ended terms, which means “including but not limited to.
- the term “based on” may be understood as “based at least in part on.”
- the term “one embodiment” may be understood as “at least one embodiment”.
- the term “another embodiment” may be understood as “at least one other embodiment”.
- a low-voltage power distribution device is generally provided with a control circuit board, on which a detecting module is provided for detecting faults, such as leakage, arc and undervoltage/overvoltage etc., and sending detection results in the form of electrical signals to a control unit.
- the control unit will determine, according to the signals, presence of a tripping condition that causes the low-voltage distribution device to trip in the circuit, so as to send a tripping trigger signal that triggers a tripping mechanism to trip.
- the tripping mechanism performs a tripping action based on the tripping trigger signal.
- the detecting module is not disposed on the control circuit board and instead powered by an individual power supply.
- the low-voltage power distribution device continues to use the control circuit board employed when using an upper incoming line, which causes many problems.
- the lower incoming line refers to connecting a main power supply to a lower interface of the low-voltage power distribution device; in such case, although the control circuit board, upon detecting the above faults, can control the tripping mechanism to perform the tripping action to disconnect the main power supply from a load circuit, the control circuit board is still charged as the main power supply is connected from the lower interface after the tripping (i.e., in the open state of the low-voltage power distribution device).
- the control circuit board can achieve various functions as long as it is charged. That is, the control units still can send, according to the tripping condition, the tripping trigger signals to the tripping mechanism which performs a tripping action based on the signals. In this event, however, the low-voltage power distribution device in the open state will not respond to the tripping action. In other words, the tripping mechanism will always perform useless operations in this case, which usually leads to burnout of the tripping mechanism and further damages the entire low-voltage power distribution device.
- some low-voltage power distribution device es with the lower incoming line disable the fault detecting mechanism after the tripping, to avoid the burnout of the tripping mechanism.
- the control unit will not receive fault signals from the fault detecting mechanism and accordingly will not send a tripping trigger signal.
- the tripping mechanism therefore will not perform actions. That is, in case of circuit faults, the circuit is still connected and the low-voltage power distribution device warns the users of the faults just by a flickering alarm light.
- Embodiments of the present disclosure provide an improved low-voltage power distribution device 200 and a method of controlling tripping of the low-voltage power distribution device 200 to solve or at least partially solve the above-mentioned and other potential problems of the conventional solutions.
- FIG 1 shows a simplified structural diagram of a detection unit and a test assembly of a low-voltage switchgear according to an example embodiment of the present disclosure.
- the improved low-voltage power distribution device 200 will be described below in conjunction with FIG 1 .
- the low-voltage power distribution device 200 of the present disclosure comprises a detection unit 100, and a control unit 202.
- the detection unit 100 is provided in the low-voltage power distribution device 200 and is used to provide a closed state signal when the low-voltage power distribution device 200 is in the closed state.
- the closed state signal may be an electrical signal, or may be other type of digital or analog signal.
- the control unit 202 is coupled to the detection unit 100. It is to be understood that the control unit 202 may be directly coupled to the detection unit 100, or may be coupled to the detection unit 100 through a filter circuit or a modulation circuit. In other words, the closed state signal of the detection unit 100 may be directly sent to the control unit 202, or may be sent to the control unit 202 after filtering or modulation.
- the control unit 202 After receiving the closed state signal, if the tripping condition still exists in the circuit, the control unit 202 will control the low-voltage power distribution device 200 to trip. It is to be understood that the low-voltage power distribution device according to the present disclosure will trigger the tripping signal only if the control unit 202 receives the closed state signal and the tripping condition is met. That is to say, in the open state, even if the tripping condition still exists, the control unit 202 will not trigger any signal because the closed state signal is not detected or received, so the tripping mechanism will not perform any action. Therefore, a closed-loop control can be achieved in the low-voltage distribution device 200 by setting the detection unit 100 to indicate the closed state. The control unit 202 can perform a clearer judgment on the state of the low-voltage distribution device 200, thereby avoiding the electric device 200 and the load circuit from damage.
- the low-voltage power distribution device 200 may further comprise a power supply 215 to supply power to at least the detection unit 100.
- the detection unit 100 only provides a closed state signal when it is powered, that is, connected to the power supply 215.
- the power supply 215 may be a step-down module provided in the low-voltage power distribution device 200. The step-down module lowers the voltage of the main power supply to provide power to the detection unit 100.
- the power supply 215 may also be a battery or the like.
- the low-voltage power distribution device 200 may further comprise a connection assembly 201 coupled to the detection unit 100.
- the connection assembly 201 can be operated to connect the detection unit 100 to the power supply 215 when the low-voltage power distribution device is in a closed state, so that the detection unit 100 is powered to provide a closed state signal.
- connection assembly 201 connects the power supply 215 with the detection unit 100 only in the closed state
- the detection unit 100 sends a closed state signal to the control unit 202.
- the detection unit 100 and the power supply 215 are disconnected. Therefore, at this time, the detection unit 100 cannot provide the closed state signal because it is not powered. This realizes the detection of the closed state through a simple detection unit 100 and the connection assembly 201.
- the conventional low-voltage power distribution device basically does not need to be changed to achieve the above-mentioned detection function, thereby saving costs while increasing reliability of the low-voltage power distribution devices.
- the detection unit 100 may be a circuit.
- the circuit can send out an electrical signal at the output when connected to the power supply 215, and the control unit 202 confirms that the low-voltage power distribution device 200 is in the closed state upon receiving the electrical signal.
- the detection unit 100 may also take any other form which can provide a closed state signal when connected to the power supply 215.
- the low-voltage power distribution device may further comprise a tripping mechanism (not shown).
- the control unit 202 performs the tripping action by providing a trip trigger signal to the tripping mechanism.
- the detection unit 100, the power supply 215, the connection assembly 201, the control unit 202, and the tripping mechanism may be provided on a control circuit board (not shown) in the low-voltage distribution device.
- the control circuit board may be an integrated circuit board or separate structures, and each module is respectively arranged in different separate structures to control each unit or module more accurately.
- connection assembly 201 comprises two conductive contacts (referred to as a first conductive contact 203 and a second conductive contact 204 for convenience of description) and a conductive member 205.
- the first conductive contact 203 is coupled to the detection unit 100, and the second conductive contact 204 is coupled to the power supply 215.
- a portion of the conductive member 205 (referred to as the first contact portion 206 for convenience of description) is coupled to the first conductive contact 203, while another portion (referred to as the first contact portion 207 for convenience of description) is operable to contact the second conductive contact 204 in a closed state, thereby connecting the detection unit 100 and the power supply 215.
- FIG 2 shows a side view of the low-voltage switchgear in the closed state according to an example embodiment of the present disclosure
- FIG 3 shows a side view of the low-voltage switchgear in the open state according to an example embodiment of the present disclosure.
- the low-voltage power distribution device 200 may have a handle 208 and a driving component 209.
- the handle 208 can be switched in two positions (referred to as a closed position and an open position for convenience of description) in response to a user's operation.
- the handle 208 is in the closed position, the low-voltage power distribution device 200 is in the closed state, and when the handle 208 is in the open position, the low-voltage power distribution device 200 is in the open state.
- the driving component 209 is pivotally provided in the low-voltage power distribution device 200.
- the driving component 209 can be driven to rotate from the first position P1 to the second position P2.
- the driving component 209 forces the second contact portion 207 to contact the second conductive contact 204, so that the second contact portion 207 contacts the second conductive contact 204 to connect the detection unit 100 to the power supply 215 in the closed state.
- the low-voltage power distribution device 200 is switched from the closed state to the open state by a tripping action to disconnect the main power supply from the load circuit. It is to be understood that the low-voltage power distribution device 200 may also be switched from the closed state to the open state through the handle 208. Whether the low-voltage power distribution device 200 is switched from the closed state to the open state due to the tripping action or the operation of the handle 208, the position of the handle 208 will be switched from the closed position to the open position accordingly.
- the driving member 209 therefore also rotates from the second position P2 back to the first position P1. At this time, the second contact portion 207 is not pressed by the driving member 209, thereby to disconnect the contact with the second conductive contact 204 to disconnect the detection unit 100 from the power supply 215.
- the conductive member 205 may further comprise a third contact portion 213, and the low-voltage power distribution device 200 further comprises a test assembly 210.
- the test assembly 210 can test the validity of the low-voltage power distribution device 200, for example.
- the test assembly 210 comprises a test unit 211, a test contact 212 and a test button 214.
- the test unit 211 may be a circuit connected to a corresponding module to be tested.
- the test unit 211 is coupled to the test contact 212, and in response to a press of a user, the test button 214 can drive the third contact portion 213 to contact the test contact 212, thereby connecting the test unit 211 to the power supply 215 to supply power to the test unit 211 in a closed state, i.e., when the second contact portion 207 is in contact with the second conductive contact 204.
- the test unit 211 may be a circuit that performs a test function. It is to be understood that the test unit 211 may also take any other form as long as it can fulfill the test functions.
- the first conductive contact 203, the second conductive contact 204, and the test contact 212 are conductive pins provided in the low-voltage power distribution device, respectively.
- the three conductive contacts adopt the form of conductive pins so that the conductive contacts can act as a fulcrum or a pivot of the movement of certain components while enabling the conductive function.
- the three conductive pins, that is, the first conductive contact 203, the second conductive contact 204, and the test contact 212 may be made of metal materials.
- the first conductive contact 203, the second conductive contact 204, or the test contact 212 may be any other forms of contact structures which are arranged individually in the low-voltage power distribution device 200 and can implement circuit conduction.
- the conductive member 205 may be a torsion spring.
- the torsion spring generally has a spiral portion and at least two free ends extending from the spiral portion (referred to as a first free end and a second free end for convenience of description).
- the spiral portion of the torsion spring serves as the first contact portion 206
- the second contact portion 207 may be a first free end
- the third contact portion 213 may be a second free end.
- the first free end and the second free end may have appropriate lengths, and may be bent or deformed so that the torsion spring can adapt to the arrangement of first conductive contact 203, the second conductive contact 204 and the test contact 212 in the low-voltage power distribution device 200.
- the low-voltage power distribution device 200 also includes an alarming mechanism (not shown), which can send an alarm to users when the fault detecting mechanism detects the tripping condition in the circuit.
- the alarming mechanism may send a light alarm, a sound alarm or a combination thereof according to the tripping condition to warn the users of the faults in need of immediate maintenance in the circuit.
- FIG 6 shows a flow block diagram 600 of a method of controlling tripping of a low-voltage power distribution device according to an example embodiment of the present disclosure.
- the closed state may be detected by the detection unit 100 as described above, that is, block 601 may be performed by the detection unit 100.
- the detection unit 100 provides the closed state information to the control unit 202 in the closed state.
- the block 601 may also be executed by any other component or unit capable of detecting the closed state.
- this block 602 it is detected whether a tripping condition associated with a low-voltage power distribution device is met.
- this block 602 may be performed by the fault detecting mechanism described above.
- the failure detecting mechanism provides a tripping condition signal to the control unit 202 when it detects that the tripping condition is met.
- the content at block 602 may also be performed by the control unit 202.
- block 601 is described before block 602, it does not mean that it can only be performed in the order described by the two blocks 601 and 602, and the method can be performed in other orders.
- block 601 and block 602 can be performed simultaneously, or the content of block 602 is executed first, and then the content of block 601 is executed.
- the low-voltage power distribution device in response to the low-voltage power distribution device 200 being in the closed state and the tripping condition being met, the low-voltage power distribution device is caused to perform a tripping action to switch the low-voltage power distribution device from the closed state to the open state.
- the block 604 may be performed by the control unit 202 described above.
- the block 604 may send a trip trigger signal to the tripping mechanism by the control unit 202 to cause the low-voltage power distribution device 200 to be tripped.
- low-voltage power distribution device 200 is tripped only if both the closed state and the tripping condition are satisfied. In this way, a closed-loop control can be achieved during the tripping control. For example, at block 605, when the low-voltage power distribution device 200 is in the open state, the tripping action will not be performed, so that null operation and burnout will not occur to the components such as the tripping mechanism, etc. related to the tripping action. At this time, at block 606, the control unit 202 is already in a standby state without triggering a signal such as a tripping signal.
- the low-voltage power distribution device 200 In addition, if it is detected that the low-voltage power distribution device 200 is in the closed state when the tripping condition is met, the low-voltage power distribution device will also be tripped and switched from the closed state to the open state. This ensures the safe use of the load circuit and the low-voltage power distribution device 200.
- the above method can be applied to a low-voltage power distribution device adopting the lower incoming line.
- this method can also be applied to any other low-voltage power distribution device that needs to detect the closed state.
- the above-mentioned tripping conditions may include, but are not limited to, at least one of overvoltage, undervoltage, short circuit, leakage, and arc fault of the circuit.
- an alert signal is provided to the user in response to the tripping condition being met.
- the user will repair the circuit or low-voltage power distribution device according to the alarm signal, thereby eliminating the fault that triggers the tripping condition. This further ensures the safe use of the low-voltage power distribution device 200.
