Description
Technical field
The utility model relates to a kind of switch, and particularly low pressure is used circuit breaker.
Background technology
Low pressure is well-known technology with circuit breaker, is used to protect power consumption equipment and switching device.This type switch adopts multipole design mostly, and wherein, every utmost point (every phase) all live wire passes switch.Be provided with the switch contact that can cut off electric current by switching mechanism in the switch, in this process, these switch contacts are broken off by switching mechanism.What use during electric current that detection is flow through from lead is the current transformer of converting unit, this current transformer be arranged on the lead and produce one with the corresponding analog converter variable of electric current.The electronics trigger element has according to this transducer inspection by variable and does not satisfy current condition, and this current condition often is meant and has or not above current threshold.If satisfy current condition, promptly surpassed current threshold, trigger element is just according to preset current-time characteristic trigger switch mechanism.Carry out it is thus clear that indication with the state of the indicator elment that receives trigger element control switch.
Its shortcoming is that form can only provide the information about the integrality of switch or trigger element for the indicator elment of one or more light-emitting diode or display.For example, with corresponding color and/or flashing rate and/or literal indication overload situations.For whole leads are comprehensively indicated, perhaps carry out the indication that to ask individually for each single lead.Prior art can also be read the triggering reason from display after triggering, perhaps access the triggering reason through communication link.
The utility model content
The purpose of the utility model provides the scheme that a kind of people's of letting a glance just can be understood the state of all leads.
The embodiment of the utility model provides a kind of switch, comprising:
Pass at least two leads of said switch,
Switch contact, it is broken off cutting off said lead by a switching mechanism,
One converting unit, its respectively have one be arranged in the current transformer on the said lead and respectively produce one with the corresponding analog converter voltage of electric current,
One electronics trigger element; Said transducer voltage is provided for said trigger element; Said trigger element compares a derivation respectively from the electric current of said transducer voltage with a current condition; When satisfying said current condition, said trigger element triggers said switching mechanism and breaks off said switch contact, and
Indicator elment, it receives said trigger element control and indicates corresponding state according to the cut-out situation that satisfies situation and respective wire of said current condition,
Every lead is established an independent indicator elment in order to the indication corresponding state, and wherein, said state indication comprises at least:
A) satisfy said current condition, and
B) cut off said electric current.
According to this solution, every lead established an independent indicator elment in order to the indication corresponding state, and wherein, the state indication comprises at least: a) have and do not satisfy current condition and b) have and do not cut off current in wire.By means of a) and b) two, if unmet current condition and do not cut off current in wire will be indicated this automatically.That is, the state of each single through-flow lead is monitored and indicated.
See that from technical standpoint simple proposal is that said indicator elment is embodied as electrooptic cell.
The utility model suggestion is embodied as light-emitting component with said electrooptic cell, in order to avoid receive exterior light according to condition effect.
A kind of scheme that can simply distinguish instruction content is to indicate different conditions with different colours.
A kind of scheme that can strengthen independence is, trigger said switch after, an external power source (a particularly battery) is connected voluntarily or can the person of being used be connected, so that be that said trigger element is supplied power.
Said current condition is preferably corresponding with one predetermined current-time response respectively.
Description of drawings
Fig. 1 is the switch sketch map; And
Fig. 2-4 is three kinds of different indication situations.
Embodiment
Hereinafter will be elaborated to the utility model with reference to accompanying drawing.
Fig. 1 is embodied as the switch 1 of low pressure with circuit breaker.Have three lead L1, L2, L3 to pass triple-pole switch 1, these leads are provided with the switch contact 2 that can cut off lead L1, L2, L3 and the electric current I 1 that from lead L1, L2, L3, flows through, I2, I3.Lead L1, L2, L3 are provided with current transformer W1, W2, W3, these current transformers be subordinated to a converting unit respectively and produce respectively one with current in wire I1, I2, the proportional transducer voltage U1 of I3, U2, U3.Transducer voltage U1, U2, U3 are offered electronics trigger element ETU.Trigger element ETU compares transducer voltage U1, U2, U3 and predetermined electric current threshold value.Generally speaking be exactly that this trigger element check has does not satisfy current condition, promptly has not surpass threshold value.If electric current I 1, I2, I3 surpass defined threshold, trigger element ETU just passes through the actuator A trigger switch M of mechanism according to predetermined current-time response, by this switching mechanism cut-off switch contact 2.Dot this process among Fig. 1.Its contact was separated from one another when switch contact 2 broke off.
Trigger element ETU comprises indicating device E, indicator elment E1, E2, E3 that it is light-emitting diode D1, D2, D3 that this indicating device has three forms.Every lead L1, L2, L3 establish independent light-emitting diode D1, D2, a D3; These light-emitting diodes are indicated the state (lead state) of corresponding lead L1, L2, L3 respectively; Promptly indicate defined threshold not have respectively and be exceeded, and indicator current I1, I2, I3 do not have and be cut off (promptly equalling zero).
Each light-emitting diode D1, D2, D3 all can show three kinds of different colours, every kind of each corresponding a kind of state of color.The mode of indication " electric current is lower than current threshold (generally being " unmet current condition ") " state is to be subordinated to light-emitting diode D1, D2, the D3 green light of associated tracks.When " electric current surpasses current threshold " state occurring, corresponding light-emitting diode D1, D2, the D3 light that turn to be yellow, " triggering " state then the light-emitting diode D1, D2, the D3 that glow of usefulness are indicated.
Fig. 2 to Fig. 4 is illustrated this with the embodiment form, wherein shows the switch 1 that is provided with indicating device E, and this indicating device is that every lead L1, L2, L3 have disposed a light-emitting diode D1, D2, D3.Three diode D1, D2, D3 green light all in Fig. 2, that is these three lead L1, L2, L3 surpass current threshold.In Fig. 3, diode D1 jaundice light (shadow region that parallel lines forms), this expression lead L1 surpasses current threshold.Then, lead L1 surpasses this situation of current threshold and impels trigger element ETU trigger switch 1, and this diode D1 with glow (the formed shadow region of cross-hatched bar) indicates, and two other light-emitting diode D2, D3 then continue green light.
Can directly read the state of every lead L1, L2, L3 in this way soon.
