Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
At present, the current in the lines of power generation, transformation, transmission, distribution and power consumption is greatly different from several to tens of thousands of amperes. In order to facilitate measurement, protection and control, the current with large difference needs to be converted into a uniform current, and the voltage on the external circuit is generally high, for example, direct measurement is very dangerous. The current transformer can play a role in current transformation and electrical isolation.
The existing ammeter comprises a current transformer which is built in the ammeter. If an electric meter is to be used to monitor industrial equipment, the power phase line connecting the power supply and the industrial equipment must pass through a current transformer built into the electric meter. The prior art is that a meter manufacturer previously uses a section of electric wire to pass through a current transformer built in the meter, and then sets two joints of the section of electric wire outside the meter. When a user installs an electricity meter, one connector of the length of wire is connected to a power source and the other connector is connected to industrial equipment.
In practice, when the electric meter is installed, the phase line of the power supply must be cut off before the electric meter can be installed between the power supply and the industrial equipment. However, when the power phase line is thick, the wiring process between the power phase line and the preset electric wire in the ammeter is inconvenient.
For the convenience of understanding the present embodiment, first, a detailed description of an electric meter disclosed in the embodiment of the present invention is provided, including: and a plurality of current transformers arranged outside the ammeter.
The current transformer can be an open type current transformer or a closed type current transformer.
Illustratively, the electricity meter includes three current transformers disposed outside the electricity meter. As shown in fig. 1, three current transformers are respectively connected to the control element 11, and the three current transformers are respectively a current transformer 12, a current transformer 13 and a current transformer 14.
Each current transformer is respectively sleeved on a corresponding measured power phase line, a plurality of power phase lines are used for supplying power to industrial equipment, and the signal output end of each current transformer is respectively connected with a control element in the ammeter and used for sending current signals collected on the power phase lines to the control element.
In the embodiment of the invention, if the current transformer is an open type current transformer, a worker can directly sleeve the open type current transformer on a power phase line corresponding to the open type current transformer in the process of monitoring industrial equipment by using the ammeter. If the current transformer is a closed current transformer, in the process of monitoring industrial equipment by using the ammeter, a worker can disconnect the connection part of the power phase line and the industrial equipment (or disconnect the connection part between the power phase line and the power supply) firstly, directly pass the power phase line through the closed current transformer, and then connect the power phase line and the industrial equipment. Both the two modes can avoid the problem that the wiring process between the power phase line and the preset electric wire in the ammeter is inconvenient because the power phase line is thicker.
Illustratively, the industrial device may include: numerical control machine tools, voltage devices, air compressors, dyeing machines, hot oil shaping machines and the like.
In an embodiment of the present invention, a cable between a power source and the industrial device may include: an A-phase power phase line, a B-phase power phase line and a C-phase power phase line. If the current transformer is an open type current transformer, when the ammeter is installed, a worker can open the open type current transformer A, then sleeve the open type current transformer A on an A-phase power phase line, finally close the open type current transformer A, and the open type current transformer A is used for sending a current signal collected on the A-phase power phase line to the control element 11. The staff can open the open-type current transformer B, then cover the open-type current transformer B on the B-phase power supply phase line, and finally close the open-type current transformer B, and the open-type current transformer B is used for sending the current signal collected on the B-phase power supply phase line to the control element 11. The staff can open type current transformer C, then overlap open type current transformer C on C looks power phase line, close open type current transformer C at last, open type current transformer C is used for sending the current signal who gathers on C looks power phase line to control element 11.
If the ammeter breaks down, the staff only needs to take down the open-type current transformer A from the A-phase power supply phase line, take down the open-type current transformer B from the B-phase power supply phase line, take down the open-type current transformer C from the C-phase power supply phase line, and in the process of taking down the three open-type current transformers, the industrial equipment is not required to be powered off, so that the production process of the industrial equipment is not influenced, and the production efficiency of the industrial equipment can be ensured.
In an embodiment of the present invention, a cable between a power source and the industrial device may include: an A-phase power phase line, a B-phase power phase line and a C-phase power phase line. If the current transformer is a closed current transformer, when the ammeter is installed, a worker can disconnect the connection part between the phase a power phase line and the industrial equipment (or disconnect the connection part between the phase a power phase line and the power supply), then pass the phase a power phase line through the closed current transformer D, and finally connect the phase a power phase line and the industrial equipment (or connect the phase a power phase line and the power supply), wherein the closed current transformer D is used for sending a current signal collected on the phase a power phase line to the control element 11. The staff can disconnect the connection between the phase B power phase line and the industrial equipment (or disconnect the connection between the phase B power phase line and the power supply), then pass the phase B power phase line through the closed current transformer E, and finally connect the phase B power phase line and the industrial equipment (or connect the phase B power phase line and the power supply), where the closed current transformer E is configured to send the current signal collected on the phase B power phase line to the control element 11. The operator may disconnect the connection between the C-phase power phase line and the industrial equipment (or disconnect the connection between the C-phase power phase line and the power supply), then pass the C-phase power phase line through the closed-type current transformer F, and finally connect the C-phase power phase line and the industrial equipment (or connect the C-phase power phase line and the power supply), where the closed-type current transformer F is configured to send the current signal collected on the C-phase power phase line to the control element 11.
In the embodiment of the invention, if one current transformer fails, other new current transformers can be used for replacing, so that the service efficiency of the ammeter is improved.
In an embodiment of the present invention, an electric meter provided in the embodiment of the present invention includes: a plurality of current transformers disposed outside the electricity meter; each current transformer is respectively sleeved on a corresponding measured power phase line, a plurality of power phase lines are used for supplying power to industrial equipment, and the signal output end of each current transformer is respectively connected with a control element in the ammeter and used for sending current signals collected on the power phase lines to the control element.
Therefore, in the process of monitoring industrial equipment by using the ammeter, as the plurality of current transformers are all arranged outside the ammeter, when the ammeter is installed, if the current transformers are open-type current transformers, workers only need to sleeve the open-type current transformers on the corresponding measured power phase lines, or if the current transformers are closed-type current transformers, the workers only need to disconnect the connection parts of the power phase lines and the industrial equipment, the power phase lines directly pass through the closed-type current transformers, and then the power phase lines are connected with the industrial equipment. The problem that the wiring process between the power phase line and the preset electric wire in the electric meter is inconvenient due to the fact that the power phase line is thicker is avoided, and therefore the technical problem that the wiring process between the power phase line and the preset electric wire in the electric meter is inconvenient in the prior art is solved, and the technical effect of improving the convenience of the wiring process between the power phase line and the preset electric wire in the electric meter is achieved.
In practical applications, in order to meet the requirement of the user for remotely controlling the electric meter, there may be a problem that the electric meter needs to communicate with the server, and in order to solve the problem, in a further embodiment of the present invention, the electric meter may further include: a communication module and the control element.

For example, the electricity meter 42 status may include: a power-off state, a networking state, a network-off state, a fault state, a normal operating state, etc. When the electricity meter 42 is in the power-off state, the red status indicator light, the green status indicator light, and the yellow status indicator light may all be turned off. When the electricity meter 42 is in a networking state, the red status indicator light may be turned on, the green status indicator light may flash at a frequency of 2 times/second, and the yellow status indicator light may be turned off. When the ammeter 42 is in the off-grid state, the red status indicator light may be turned on, the green status indicator light may flash at an arbitrary frequency, and the yellow status indicator light may be turned off. When the ammeter 42 is in a fault state, the red status indicator light may be turned on, the green status indicator light may flash at a frequency of 0.5 times/second, and the yellow status indicator light may be made arbitrary. When the electricity meter 42 is in a normal operation state, the red status indicator lamp may be turned on, the green status indicator lamp may flash at a frequency of 1 time/second, and the yellow status indicator lamp may be turned on.
In this embodiment of the present invention, the red status indicator is connected to the control element 11, and is configured to switch according to the received control signal of the red status indicator. The green status indicator lamp is connected with the control element 11 and is used for switching according to the received control signal of the green status indicator lamp.

Therefore, the work efficiency of the worker can be improved. Meanwhile, the operation safety of the ammeter 42 can also be improved.
In practical applications, if the staff places the electric meter in a place where the signal shielding is serious, the electric meter may not receive the wireless network signal, or only receive the weak wireless network signal, and then the electric meter cannot normally communicate with the server, in order to solve the problem, in a further embodiment of the present invention, the electric meter may further include: an antenna and a suction cup.
By way of example, the length of the antenna may be set to 1 meter.
