Describe below with reference to the accompanying drawings the utility model embodiment in detail.
Fig. 1 is the flow chart of method 100 of the trip free of the schematically illustrated neutral pole that is used for switch according to embodiment of the present utility model.
As shown in fig. 1, method 100 110 in, the voltage of the leading-out terminal of the phase utmost point of sense switch.In 120, trigger actuator based on the voltage of this leading-out terminal, with the trip status of the neutral pole of controlling described switch.
Therefore, according to the utility model embodiment, because trigger actuator and promoted the dropout of neutral pole by actuator by the voltage based on the leading-out terminal of the phase utmost point, so the dropout of neutral pole is a mechanical process fully, thereby corrosion and the welding problems of contact have been avoided, prolong the useful life of element, saved cost.In addition, the breaking capacity of the utility model embodiment centering utmost point does not require, thereby can use the neutral pole that does not have breaking capacity or have faint breaking capacity.
Fig. 2 is the block diagram that illustrates according to the demonstrative structure of the equipment 200 of the trip free of the neutral pole that is used for switch of embodiment of the present utility model.
As shown in Figure 2, equipment 200 comprises detector 201, controller 202 and actuator 203.
Particularly, detector 201 is for detection of the voltage of the leading-out terminal of the phase utmost point of switch, controller 202 is used for triggering actuator based on the voltage of this leading-out terminal, and actuator 203 is used for the trip status of the neutral pole of the described switch of control under the control of described controller.
Therefore, according to the utility model embodiment, because trigger actuator and promoted the dropout of neutral pole by actuator by the voltage based on the leading-out terminal of the phase utmost point, so the dropout of neutral pole is a mechanical process fully, thereby corrosion and the welding problems of contact have been avoided, prolong the useful life of element, saved cost.In addition, the breaking capacity of the utility model embodiment centering utmost point does not require, thereby can use the neutral pole that does not have breaking capacity or have faint breaking capacity.
Here, when the voltage that detects leading-out terminal when detector 201 was equal to or higher than a predetermined voltage threshold, controller 202 did not trigger actuator 203, thereby the neutral pole of switch is not threaded off; And when the voltage that detects leading-out terminal when detector 201 was lower than this predetermined voltage threshold, described controller 202 triggered actuators 203, threads off thereby actuator 203 promotes the neutral pole of described switch.
Should be noted in the discussion above that those skilled in the art can as required or test and determine this predetermined voltage threshold, so that this predetermined voltage threshold is suitable for actual needs and can allows certain voltage fluctuation.
Fig. 3 is the exemplary circuit diagram that illustrates according to the first implementation 300 of the equipment of the trip free of the neutral pole that is used for switch of the utility model embodiment.
In Fig. 3, actuator is depicted as magnetictrip, still, the utility model embodiment is not limited to this, and those skilled in the art can select other suitable devices according to design requirement and operational environment, as long as its action of can threading off.In addition, controller is depicted as PCBA.
As shown in Figure 3, in the first implementation 300, switch 302 comprises a neutral pole N and a utmost point P mutually, and switch 302 for example can be the circuit breaker such as residual current circuit breaker (RCBO) or miniature circuit breaker (MCB).Although in the first implementation 300 switch 302 being depicted as is the 1P+N structure, but the utility model is not limited to this, those skilled in the art can understand that this switch 302 can also be heterogeneous structure, such as 2P+N, 3P+N, 4P+N etc., as will be described.
Here, the first implementation 300 is depicted as the upper end power taking with switch 302, be neutral pole N with the upper end of utmost point P mutually be that end of incoming cables and its lower end are leading-out terminal, but those skilled in the art can understand, except end of incoming cables and leading-out terminal on the contrary, be used for the similar of the connected mode of lower end power taking and upper end power taking, repeat no more here.
Particularly, in the first implementation 300, the zero line of PCBA 303 is by mechanical organ K(switching device for example) be connected to the leading-out terminal of the neutral pole N of switch 302.Here, mechanical organ K is the neutral pole N that is suspended in switch for the zero line that makes PCBA 303, and namely when neutral pole N is not closed, PCBA 303 does not connect with the neutral pole N of switch.This suspension design is just in order to guarantee the safety of installation personnel, and and inessential.
The live wire of PCBA 303 is connected to the end of incoming cables of the phase utmost point of switch 302, the voltage of the leading-out terminal of the phase utmost point P of detector 304 sense switches 302, and detection signal sent among the PCBA 303.Magnetictrip 301 can be connected in series with the live wire of PCBA 303, and couples with the neutral pole N of switch 302.
When the phase utmost point P of switch 302 closure, the voltage of its leading-out terminal is equal to or higher than a predetermined voltage threshold, for example the voltage of this leading-out terminal can be 220V, detector 304 detects this high voltage, thereby PCBA 303 does not trigger magnetictrip 301 and magnetictrip 301 is not taked action, so the neutral pole N of switch 302 does not thread off.
As the phase utmost point P of switch 302 because disjunction, magnetic are taken off, when Re Tuo or other reasons are threaded off, the voltage of its leading-out terminal is lower than decides voltage threshold, for example the voltage of this leading-out terminal can be 0V, detector 304 detects this low-voltage, thereby PCBA 303 triggers the action of magnetictrip 301, with the neutral pole N dropout of pull switch 302.This process may cause for example being between the 0.5s to 2s, and can controlling this time of delay by circuit design from the dropout of phase utmost point P to one dropout of neutral pole N short time of delay.
At this moment, in circuit, because phase utmost point P does not have electric current, thereby does not have electric current in the circuit yet, so the dropout of neutral pole N is a mechanical process fully.Therefore, avoid corrosion and the welding problems of contact, prolonged the useful life of element.In addition, this process does not need neutral pole N to have breaking capacity, thereby can use the neutral pole that does not have breaking capacity or have faint breaking capacity in circuit, has expanded the scope of application of circuit.
Although in Fig. 3, detector 304 is depicted as the parts that separate with PCBA 303, but those skilled in the art can understand, also can utilize the existing device of PCBA 303 inside to come the voltage of leading-out terminal of the phase utmost point P of sense switch 302, as long as the voltage that this device can this leading-out terminal of sensing and with its notice PCBA 303.
Fig. 4 is the exemplary circuit diagram that illustrates according to the second implementation 400 of the equipment of the trip free of the neutral pole that is used for switch of the utility model embodiment, and wherein, switch 402 be the 3P+N structure, and power taking on being.
When switch 402 is heterogeneous structure, can selects among these a plurality of phase utmost point P to bring in the outlet of neutral pole N next-door neighbour's the phase utmost point and detect its voltage.
In addition, in the second implementation 400, except the voltage of the leading-out terminal of a phase utmost point P, detector 404 also detects external signal, and triggers the action of magnetictrip 401 based on the combination of the voltage of this external signal and leading-out terminal as the PCBA 403 of controller.The voltage that should be noted that leading-out terminal and external signal are different signals, and this external signal can not be input to phase utmost point P.
For example, this external signal can be the instruction that is used to indicate the user that neutral pole N threads off or the instruction of internal system.Based on this instruction, even the voltage of the leading-out terminal of phase utmost point P is equal to or higher than predetermined voltage threshold, PCBA403 also triggers magnetictrip 401, so that the dropout of the neutral pole N of magnetictrip 401 pull switchs.
According to the utility model embodiment, the dropout part of neutral pole N can be single face dropout part, for example single face gear selenodont groove or unidirectional shared release lever are not threaded off together so that do not drive neutral pole N when phase utmost point P threads off, but can drive phase utmost point P when neutral pole N threads off threads off together.It should be noted that, the single face dropout part of neutral pole N is not limited to single face gear selenodont groove and unidirectional shared release lever, those skilled in the art can use other mechanism as required, thread off together and can drive phase utmost point P thread off together when neutral pole N threads off as long as it can realize not driving neutral pole N when phase utmost point P threads off.
In addition, external signal can be one or more in overvoltage signal, under-voltage signal and the shunt opening signal, perhaps can be other any signals that can be characterized as being voltage, comprises temperature, humidity etc.
Here, can adopt with door (AND) and be used as detector 404.But the utility model is not limited to this, and those skilled in the art can understand, logical circuit, element or even the combinational circuit that can also adopt other according to characteristic and the design requirement of each external signal.
Therefore, according to embodiment of the present utility model, can also come in conjunction with other external signals the on/off of control switch, and drive the dropout of phase utmost point P by the dropout part of neutral pole N, this has expanded the range of application of product greatly, and has improved the fail safe of product.
For example, when the voltage of the leading-out terminal of phase utmost point P is equal to or higher than predetermined voltage threshold, if detector 404 detects the overvoltage signal, then according to the result of logic and operation, controller still will trigger magnetictrip 401 with the neutral pole N dropout of pull switch 402, and the dropout part of neutral pole N drive phase utmost point P threads off together.Like this, can make product avoid overvoltage, the impact such as under-voltage.
