Discharge tube 1000 and the air gap biggest advantage of comparing are that performance is stablized, and factor affected by environment is smaller.
Further, it is wound with conducting wire outside coil 820, the second revolving part 200 of conducting wire one end and releasing structure is connected,
The other end and the second conducting wire 920 are connected, also, coil 820 is internally provided with mandril, is having high current (such as thunder and lightning) to pass through
When, mandril 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 conducting wire 920.In the case where there is high current to pass through, electric current flows to coil by the second revolving part 200 first
820, the mandril in coil 820 ejects so that the second revolving part 200 is separated with stationary contact, disconnects so as to cause circuit.
Due to being provided with above-mentioned clamp assemblies 810, so that the distance between the first gap and the second gap are fixed, namely
The distance between first conducting wire 910 and the second conducting wire 920 are fixed, and the first conducting wire 910 and the second conducting wire 920 can be protected apart from fixation
Gap stable discharging is demonstrate,proved, so that entire back-up protection device steady operation.
Further, the back-up protection device in the present embodiment further includes having upper contact terminal and lower contact terminal, is above connect
Contravention and the electrical connection of the second revolving part.Lower contact terminal is electrically connected with the second conducting wire 920 of gap protection module.
Further, the back-up protection device in the present embodiment further includes having upper housing and lower case, upper housing and lower casing
Body dismantling connection, and it is formed with accommodation space in the assembled state.Wherein, the handle in the manual switch of releasing structure stretches out
Above-mentioned accommodation space, that is, handle is located at the outside of overall housing.In addition, gap protection module is located at the inside of overall housing
And it is located at the side of releasing structure.Upper contact terminal and lower contact terminal are located at the two sides of interior accommodating space.This reality
It applies the back in example to switch using modular design scheme, compact overall structure, performance is stablized.
To the course of work of back-up protection device, detailed description are as follows below:
In normal operating conditions, electric current flows to coil 820 from the second revolving part 200 of releasing structure, flows from coil 820
To the second conducting wire 920, the controller switching equipment in downstream is then flowed to from the second conducting wire 920.At this point, due to the first conducting wire 910 and second
The presence in gap between conducting wire 920, so that the first conducting wire 910 and the second conducting wire 920 are to disconnect, electric current can not be led by first
Line 910 flows to the second conducting wire 920.
In the case of high current (such as thunder and lightning) passes through, it is unaffordable excessively electric that back-up protection device generates normal insulation part
Pressure, under overvoltage condition, the gap between the first conducting wire 910 and the second conducting wire 920 is breakdown so that the first conducting wire 910
It is connected with the second conducting wire 920, with the conducting of the first conducting wire 910 and the second conducting wire 920, a large amount of lightning currents leak into the earth, make
Voltage sharp fall, to protect the insulator on route that flashover or breakdown will not occur.Also, high current passes through coil
After 820, mandril in coil 820 is moved due to magnetic field effect to open the first of releasing structure the rotation to the direction of releasing structure
Part 100, the first revolving part 100 rotate after the active force by mandril and the second revolving part 200 are driven to be gradually distance from stationary contact,
So that circuit disconnects, the controller switching equipment that high current flows to downstream is avoided.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
