Structure and gap protection module 800, gap protection module 800 include clamp assemblies 810 and coil 820, and coil 820 is installed
In clamp assemblies 810.
Further, clamp assemblies 810 include gripping base 811 and are removably installed on gripping base 811
The first lateral holding portion 812 and the second lateral holding portion 813 of side;It is formed between the lateral holding portion 812 of gripping base 811 and first
The second gap is formed between first gap, the lateral holding portion of gripping base 811 and second.
Further, back-up protection device also includes the first wire 910 and the second wire 920, the end of the first wire 910
The first gap is stretched into, the second gap is stretched into the end of the second wire 920, also, the first wire 910 stretches into the part in the first gap
It is parallel with the part that the second wire 920 stretches into the second gap.In addition, being set in the end towards releasing structure of the first wire 910
Stationary contact is equipped with, the stationary contact namely the stationary contact hereinbefore addressed.
Further, Figure 13 is refer to, gap protection module 800 can be substituted by gas-discharge tube 1000, at this more
In further scheme, the gap protection module 800 is mutual alternative feature with gas-discharge tube 1000.In assembled state
Under, the first wire 910 is connected with the side of gas-discharge tube, and the second wire 920 is connected with the opposite side of gas-discharge tube.Gas
Discharge tube 1000 and the air gap biggest advantage of comparing are that performance is stable, and factor affected by environment is smaller.
Further, it is wound with wire outside coil 820, the second revolving part 200 of wire one end and releasing structure is turned on,
The other end is turned on the second wire 920, also, coil 820 is internally provided with push rod, is passed through there is high current (such as thunder and lightning)
When, push rod stretches out under magnetic induction effect.Under normal circumstances, electric current flows to coil 820 from the second revolving part 200, then by line
Circle 820 flows to the second wire 920.There is high current in the case of, electric current flows to coil by the second revolving part 200 first
820, the push rod in coil 820, which is ejected, causes the second revolving part 200 to be separated with stationary contact, so as to cause circuit to disconnect.
The clamp assemblies 810 above-mentioned due to being provided with so that the distance between the first gap and the second gap are fixed, namely
The distance between first wire 910 and the second wire 920 are fixed, and the first wire 910 and the second wire 920 can be protected apart from fixation
Gap stable discharging is demonstrate,proved, so that whole back-up protection device steady operation.
Further, the back-up protection device in the present embodiment also includes contact terminal and lower contact terminal, above connects
Contravention and the electrical connection of the second revolving part.Lower contact terminal is electrically connected with the second wire 920 of gap protection module.
Further, the back-up protection device in the present embodiment also includes upper shell and lower house, upper shell and lower casing
Body dismounting connection, and receiving space is formed with the assembled state.Wherein, the handle in the hand switch of releasing structure stretches out
Above-mentioned receiving space, i.e. handle is located at the outside of overall housing.In addition, gap protection module is located at the inside of overall housing
And positioned at the side of releasing structure.Upper contact terminal and lower contact terminal distinguish the both sides of internally positioned receiving space.This reality
Apply the switch of the back in example and use modular design, compact overall structure, performance is stable.
Course of work detailed description below to back-up protection device is as follows:
In normal operating conditions, electric current flows to coil 820 from the second revolving part 200 of releasing structure, is flowed from coil 820
To the second wire 920, the controller switching equipment in downstream is then flowed to from the second wire 920.Now, due to the first wire 910 and second
The presence in gap between wire 920, so that the first wire 910 and the second wire 920 are to disconnect, electric current can not be led by first
Line 910 flows to the second wire 920.
High current (such as thunder and lightning) by the case of, back-up protection device produce normal insulation part it is unaffordable excessively electric
Pressure, under overvoltage condition, the gap between the first wire 910 and the second wire 920 is breakdown so that the first wire 910
Turned on the second wire 920, with the conducting of the first wire 910 and the second wire 920, a large amount of lightning currents leak into the earth, make
Voltage significantly declines, so as to protect the insulator on circuit to occur flashover or puncture.Also, high current passes through coil
After 820, push rod in coil 820 is moved to push up the first rotation of exoneration buckle structure due to magnetic field effect to the direction of releasing structure
Part 100, the first revolving part 100 rotates after the active force by push rod and drives the second revolving part 200 to be gradually distance from stationary contact,
