The side of dagger is equipped with positioning column, and the positioning column includes the first positioning column and the second positioning column, divides on first positioning column
Torsion spring and partition plate are not cased with, and the top of the support column is fixedly connected with one end of torsion spring.
Two support plates that stretch out that one is long and the other is short respectively as a kind of optimal technical scheme of the utility model, on the partition plate,
Angle between two support plates is 60 degree.
Compared with prior art, the beneficial effects of the utility model are：The protection of this kind of SPD Surge Protector tripping mechanism
Device, can effectively cut off because of high temperature alloy wire drawing and prevent high-voltage arc discharge, avoid because high temperature alloy slowly melts, in pulling force
Under the action of spring, alloy wire drawing occurs between varistor pin and lever, causes protector to fail, so as to prevent accident
Generation, there is very high circuit loop safety coefficient.

Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment, based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained, shall fall within the protection scope of the present invention.
- 2 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of guarantor of SPD Surge Protectors tripping mechanism
Protection unit, including extension spring 1, lever 2, torsion spring 3, partition plate 4, pressing plate 5 and base 6, the right end of the extension spring 1 pass through
Hook is fixedly connected with base 6, and the left end of the extension spring 1 is connected by linking up with the upper end of pressing plate 5, the extension spring
1 lower section is equipped with lever 2, and varistor pin 7 is equipped between the end of the lever 2 and pressing plate 5, and the base 6 is equipped with
Support column 8, the side of the support column 8 are equipped with positioning column, and the positioning column includes the first positioning column 9 and the second positioning column 10,
Torsion spring 3 and partition plate 4 are cased with first positioning column 9 respectively, the top and one end of torsion spring 3 of the support column 8 are fixed
Connection.
Stretch out one is long and the other is short two support plates on partition plate 4 respectively, the angle between two support plates is 60 degree.
Concrete principle：In use, torsion spring 3 and partition plate 4 are sleeved on the first positioning column 9, positioned by torsion spring 3 and second
Column 10 limits the position of partition plate 4, and when disconnecting first time, as shown in Fig. 2, when varistor degradation failure, electric current is slow
Increase, pressing plate 5 apply lever 2 pressure by extension spring 6, and alloy absorbs heat and creep occurs, delays under the effect of the pressure
Slow elongate forms B alloy wire, reaches certain position, and lever 2 touches partition plate 4, and partition plate 4 moves to varistor pin 7 and lever 2
Between, cut off B alloy wire and isolation is formed between varistor pin 7 and lever 2, prevent high-voltage arc discharge phenomenon from occurring.
The protective device of this kind of SPD Surge Protector tripping mechanism, by effectively cutting off because of high temperature alloy wire drawing and preventing
High-voltage arc discharge, avoids because high temperature alloy slowly melts, under the action of tension spring, is sent out between varistor pin and lever
Intercrescence gold wire drawing, causes protector to fail, so as to prevent the generation of accident, has very high circuit loop safety coefficient.
Finally it should be noted that：The above descriptions are merely preferred embodiments of the present invention, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify the technical solution described in foregoing embodiments, or to which part technical characteristic
