Abstract
The utility model discloses a surge protector, comprising a protector body, a protection module, a breakdown failure disconnector, a thermal failure shedding device and a piezoresistor, wherein the breakdown failure disconnector, the thermal failure shedding device and the piezoresistor are arranged in the protection module. An L1 live wire slot, an L2 live wire slot, an L3 live wire slot and a zero wire slot are arranged in an upper part of the protector body. The protection module is installed in the protector body. A front end surface of the protection module is provided with a module label. The module label is internally provided with a through slot. The through slot is internally provided with an indicating lamp. The L1 live wire slot, the L2 live wire slot, the L3 live wire slot and the zero wire slot are serially connected with the breakdown failure disconnector, the thermal failure shedding device and the piezoresistor in the protection module respectively. By additionally providing the failure disconnector in the protection module, when the protector is overheated to breakdown the failure disconnector, the failure disconnector can disconnect with a power grid automatically, so that current-using equipment on the power grid is effective protected.
Description
Technical field
The utility model relates to a kind of Surge Protector.
Background technology
Thunderbolt and other circuit abnormalities can cause moment to produce great surge voltage; surge voltage can produce harm greatly to electrical equipment; especially for power supply; once damage because surge voltage causes power supply; the whole relevant electric system that can cause being subject to power supply to be controlled loses power supply and even damages, so Surge Protector is the requisite of protective device and components and parts.
Summary of the invention
Technical problem to be solved in the utility model is that the needs that cannot well meet people for solving some Surge Protectors in prior art wait defect, and then provides a kind of protection effective, and easy accessibility is simple to operate, the Surge Protector of long service life.
The utility model is achieved through the following technical solutions: a kind of Surge Protector, comprise protector body, protection module, in protection module, puncture inefficacy disconnector, the thermal failure protector body top described in device and varistor that comes off is respectively equipped with L1 hot slot, L2 hot slot, L3 hot slot and neutral slot, described protection module is arranged in protector body, described protection module front end face is provided with a module label, in described module label, be provided with groove, in described groove, be provided with indicator light, inefficacy in the described protection module device that comes off, thermal failure come off device and varistor, described L1 hot slot, L2 hot slot, L3 hot slot and neutral slot separately with the inefficacy device that comes off, come off device and varistor of thermal failure connected successively
As preferred version, the circuit in described protector adopts three-phase four-wire system to connect.
As preferred version, described protection module is detachable connection with protector body.
As preferred version, described each varistor is respectively at the PE line parallel join in circuit.
The beneficial effects of the utility model are: the utility model by increasing inefficacy release unit in protector module; when protector can come off it automatically because crossing thermal breakdown inefficacy release unit from electrical network; provide index signal simultaneously; thereby effectively protected the power consumption equipment on electrical network; and easy accessibility is convenient to staff's replacing, improved our operating efficiency.
Accompanying drawing explanation
For ease of explanation, the utility model is described in detail by following specific embodiment and accompanying drawing.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is electrical schematic of the present utility model.
Embodiment
As shown in Figure 1, a kind of Surge Protector of the present utility model, comprise protector body 1, protection module 12, in protection module 12, puncture inefficacy disconnector 5, thermal failure come off device 6 and varistor 7, described protector body 1 top is respectively equipped with L1 hot slot 11, L2 hot slot 10, L3 hot slot 9 and neutral slot 2, described protection module 12 is arranged in protector body 1, described protection module 12 front end faces are provided with a module label 4, in described module label 4, be provided with groove 8, in described groove 8, be provided with indicator light 4, inefficacy in described protection module 12 device 5 that comes off, thermal failure come off device 6 and varistor 7, described L1 hot slot 11, L2 hot slot 10, L3 hot slot 10 and neutral slot 2 separately with the inefficacy device 5 that comes off, come off device 6 and varistor 7 of thermal failure connected successively.
As preferred version, the circuit in described protector adopts three-phase four-wire system to connect.
As preferred version, described protection module 12 is detachable connection with protector body 1.
As preferred version, described each varistor 7 is respectively at the PE line parallel join in circuit.
The utility model in use; article three, phase line and zero line DuiPE line army are provided with protective circuit; protector is in high resistance state under normal circumstances; when electrical network is because thunderbolt or other reason are while occurring overvoltage surge; protector will be immediately in nanosecond conducting rapidly in the time; surge is introduced to the earth by voltage, thereby protected the power consumption equipment on electrical network.When this surge voltage is by protector, and after disappearing, protector changes to high resistance state again, thereby does not affect the normal operation of electrical network.
The beneficial effects of the utility model are: the utility model by increasing inefficacy release unit in protector module; when protector can come off it automatically because crossing thermal breakdown inefficacy release unit from electrical network; provide index signal simultaneously; thereby effectively protected the power consumption equipment on electrical network; and easy accessibility is convenient to staff's replacing, improved our operating efficiency.
The above, be only embodiment of the present utility model, but protection range of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claims were limited.
