Description
Technical field
The utility model relates to a kind of overvoltage protection, especially a kind of surge protector with anti-lightning strike function, the indication of band alarm state.
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: by designing a kind of structure, simple in structure, thread off sensitive, reliable alarm surge protector guarantee that the piezo-resistance that lost efficacy in time, break away from and output alarm signal from circuit reliably.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of surge protector; comprise shell; be arranged on first electrode of shell both sides; second electrode and the piezo-resistance and the trip gear that are positioned at enclosure; described trip gear comprises third electrode; copper litz wire; push rod; slide block and release piece; copper litz wire one end and release piece welding; release piece is by low temperature scolding tin and third electrode welding; the copper litz wire other end and the welding of second electrode; push rod one end is connected with sensitive switch; and top stem casing is connected to first spring of compression; the push rod other end peaks on the slide block; be socketed with second spring of compression on the extending area of slide block one end and peak on the outer casing inner wall; first electrode and piezo-resistance simultaneously are electrically connected, and third electrode and piezo-resistance another side are electrically connected.
Be arranged to a rare piezo-resistance in the described shell.
In order to know the show state of seeing warning mark clearly, offer circular transparent window on the described shell, the dropout mode of trip gear is a linear slide, first spring that compresses during dropout is replied its normal condition and is driven push rod triggering sensitive switch; Second spring of compression is replied its normal condition and driving sliding block and make form red by green commentaries on classics.
The beneficial effects of the utility model are: surge protector of the present utility model, and the trip gear of employing linear slide, sensitive more reliable, simple in structure, help suitability for industrialized production.

Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Surge protector as shown in Figure 1; comprise shell 1; be arranged on first electrode 2 of shell 1 both sides; second electrode 3 and the piezo-resistance 4 and the trip gear 5 that are positioned at shell 1 inside; trip gear 5 comprises third electrode 51; copper litz wire 54; push rod 52; slide block 53 and release piece 55; copper litz wire 54 1 ends and release piece 55 welding; release piece 55 is by low temperature scolding tin and third electrode 51 welding; copper litz wire 54 other ends and 3 welding of second electrode; push rod 52 1 ends stretch out shell 1 housing and are connected with sensitive switch 52-2; and be socketed with the first spring 52-1 of compression between push rod 52 and shell 1 inner walls; push rod 52 other ends peak on the green slide block 53; the extending area of slide block 53 1 ends peaks on the inwall of shell 1 housing; and be socketed with the second spring 53-1 of compression on the extending area; first electrode 2 is electrically connected with piezo-resistance 4 one sides, and third electrode 51 is electrically connected with piezo-resistance 4 another sides.
Offer a transparent circular form 6 on the shell 1 and be positioned at directly over the slide block 53, the dropout mode of trip gear 5 is a linear slide, and the first spring 52-1 that compresses during dropout replys its normal condition and drives push rod 52 triggering sensitive switch 52-2; The second spring 53-1 of compression replys its normal condition and drives green slide block 53 and make form 6 red by green commentaries on classics, guarantees in time to notify the user after surge protector damages.
The course of work of this surge protector: the pressure sensitive voltage that surpasses described piezo-resistance 4 when a certain overvoltage; piezo-resistance 4 will be generated heat; if temperature surpasses the fusing point of described low temperature soldering; the low temperature soldering will be melted; second electrode 3 is connected with release piece 55 by copper litz wire 54; disconnect by the interface that low temperature scolding tin is connected with third electrode 51 with release piece 55, thereby surge protector cuts off from electric power system.The first spring 52-1 and the second spring 53-1 are in the initial position of compressive state, when trip gear 5 actions, peak at push rod 52 on the slide block 53 and break away from slide blocks 53 and move upward, the first spring 52-1 moves to its normal condition, promote described push rod 52 impels sensitive switch 52-2 action, triggering signal; Simultaneously, the second spring 53-1 moves to its normal condition, impel green slide block 53 to left, and green originally circular fault form 6 just has been full of redness.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
