Existing bad problem.
The outer rim both sides of the modular cartridge 1 in the lightning protection device of the present embodiment gradually increase in sector from the bottom to top, in the mould
The top of block box 1 forms the handgrip for launching so that is easily extracted upwards when changing modular cartridge, gives the maintenance of equipment personnel side of bringing
Just.
Phase line electrode 3a and the lower end of dropout piece 6 on the inner pressure sensitive resistance 3 of the modular cartridge 1 in the lightning protection device of the present embodiment
Between the low temperature scolding tin 21 that is welded, use the special scolding tin that 140 DEG C of low temperature can just melt, it is therefore an objective to avoid lightning protection component
The adverse effect produced to power circuit during failure；Because as the piezo-resistance 3 of lightning protection component if subjected to for a long time
Overvoltage impact can produce aging or even puncture, it can be common that when piezo-resistance 3 is damaged inside occur short circuit, can thus make
Into the tripping operation of power circuit；Therefore, the characteristics of serious heating can be produced when being broken down using piezo-resistance 3, passes to heat
Between phase line electrode 3a and dropout piece 6 on low temperature scolding tin 21, low temperature scolding tin 21 melts in advance than the conventional scolding tin of 230 DEG C of fusing point,
Piezo-resistance 3 and power circuit can be disconnected rapidly, it is ensured that do not disturbed by power-off with electric line；Using the de- of low temperature scolding tin 21
The change and observation of marker sheet color become the annesl of color lump 1b in button, observation indicating window 1a, form when using lightning protection device
Multiple early warning and security protection.
As shown in figure 4, the modular cartridge 1 and module base 2 in the lightning protection device of the present embodiment are in normal operating conditions after connecting
When, the phase line pin 7 and zero line pin 8 of the bottom of the modular cartridge 1 be each passed through after the pin holes 2e of module base 2 with it is internal two
The phase line jack 10a and zero line jack 11a of terminal plate are mutually seated, and the piezo-resistance 3 itself is in the serviceable condition of normal temperature,
Therefore the tin point between phase line electrode 3a and dropout piece 6 by low temperature scolding tin 21 is securely joined together, in such annesl piece 4
Portion is just subject to the middle part of dropout piece 6 thrust to the left, and the annesl piece 4 is just deflected counterclockwise around locating dowel 1d so that annesl
The green mark piece 4b of the upper end of piece 4 falls in the range of observation of the top indicating window 1a of modular cartridge 1, and green means that lightning protection device is in
Normal operating conditions, deflecting for the annesl piece 4 causes that the small extension spring 5 of top is in extended state again, also so that under annesl piece 4
The movable ram 4e at end be in it is to the right be downwardly projected state, the movable ram 4e just with button hole 2f on module base 2 in
Inching button 18 is tightly pressed together, and the shell fragment of the lower section of inching button 18 is pushed so that the contact of microswitch 13 normally opened and
Normally-closed contact is changed, and contact state now is passed on the pin of three core terminals 17 by wiring board 16, so in remote signalling interface
On 12, it is possible to read lightning-protection module it is normal when contact state signal, signal is such as connected to by monitoring room by line again；Just
The working condition of live thunder resisting equipment can in the distance be understood.
As shown in figure 5, the modular cartridge and module base in the lightning protection device of the present embodiment are in failure trip status after connecting when,
Although the phase line pin 7 and zero line pin 8 of the bottom of the modular cartridge 1 are still divided to and two phase lines of terminal plate in the inside of module base 2
Jack 10a and zero line jack 11a are mutually seated, but the piezo-resistance 3 itself has been in abnormal febrile state, therefore phase
The tin point of low temperature scolding tin 21 has melted between line electrode 3a and dropout piece 6, and the top of such annesl piece 4 is just subject to small extension spring 5
Active force to the right, the annesl piece 4 is just deflected clockwise around locating dowel 1d so that the red marker piece of the upper end of annesl piece 4
4a falls at the top of modular cartridge in the range of observation of indicating window 1a, and red means that lightning protection device is in failure abnormal condition, annesl
The deflection of piece 4 causes that the movable ram 4e of lower end is in upward retracted state to the left again, and the movable ram 4e allows for micro-
The shell fragment of the dynamic lower section of button 18 is appeared on the stage so that the normally opened and normally-closed contact of the contact of microswitch 13 resets, by the contact changed
State is passed on the pin of three core terminals 17 still through wiring board 16, and so on remote signalling interface 12, reading is lightning protection mould
Block is abnormal, failure when contact state signal, again by although it is understood that live lightning protection in holding wire in the distance monitoring room
The abnormal state of equipment.
A kind of Aftercurrent protecting equipment lightning protection device of the present embodiment, using nonlinear lightning protection component, is combined into three
Pluggable lightning-protection module, can be attempted by Aftercurrent protecting equipment after being assemblied on the module base of integral type, play lightning protection, prevent
Surge is acted on；The lightning protection device not only pluggable replacing of lightning-protection module, and indicated with lightning protection failure state, connect with long-range remote signalling
Mouthful, while also by the color change of modular cartridge front temperature-sensitive color lump, the temperature rise of the lightning protection component that can give warning in advance finds anti-in time
The failure of thunder module, it is ensured that the safe handling of Aftercurrent protecting equipment anti-lightening protector.
Above-described embodiment should not in any way limit the utility model, all by the way of equivalent or equivalency transform
The technical scheme of acquisition is all fallen within protection domain of the present utility model.
