Description
Technical field
The utility model relates to a kind of overvoltage protection, the higher surge protector of especially a kind of reliability.
Background technology
Surge protector is a kind of low-voltage variation device commonly used; under normal circumstances; it is in high impedance status; in case and circuit is because of thunderbolt or other reason when surge occurring; its meeting conducting in the extremely short time; lightning current or overvoltage are introduced the earth by earth connection, from then on the equipment on the protection circuit.When surge protector causes deterioration because of a variety of causes, this moment, surge protector can swash acute heating, thereby made the trip gear action in the surge protector, and surge protector and circuit are broken away from, and prevented surge protector " short circuit ", and line accident is magnified.
Adopt piezo-resistance that power-supply system is carried out lightning protection, must solve following two problems: 1, piezo-resistance short-circuit inefficacy often must in time break away from from electrical network, otherwise will produce overload, even cause the generation of fire.2, behind the pressure responsive resistor failure, the lightning protection device how to notify administrative staff to change inefficacy in time guarantees the normal operation of protected equipment.
To above problem, different in the market solutions is a lot, as: the short circuit after the mode of the two ends of piezo-resistance series connection temperature safety tube, electric current protective tube is avoided losing efficacy, and the scheme that the sticking temperature fuse is reported to the police on the piezo-resistance body.But these scenario-frame complexity, complex production process are unfavorable for suitability for industrialized production.
The utility model content
The technical problems to be solved in the utility model is: in order to solve the shortcoming and defect of above-mentioned existence, provide a kind of simple in structure, adopt the surge protector of the trip gear of linear slide.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of surge protector; have base and module; the both sides of module are provided with first electrode and second electrode; module comprises lock pin and is positioned at the trip gear and the piezo-resistance of lock pin both sides; trip gear comprises third electrode; slide block; copper pigtail lines and the activity template that is arranged on the slide block; third electrode is fixedlyed connected with activity template; one end of copper pigtail lines is fixedlyed connected with activity template; the other end is fixedlyed connected with second electrode; also be provided with the compression spring in the lock pin; the compression spring peaks at the inboard of slide block, the piezo-resistance and first electrode; third electrode is electrically connected.
In order to strengthen the reliability of surge protector, on activity template, have oval-shaped hole, slide block is provided with and the corresponding projection in oval-shaped hole, and activity template and third electrode weld by low-melting alloy.Copper pigtail lines and activity template, the welding of second electrode, the dropout mode of trip gear is a linear slide, the compression spring is at least two.
The beneficial effects of the utility model are that the utility model adopts the trip gear of linear slide, and is sensitive more reliable, simple in structure, helps suitability for industrialized production, good reliability.
