Abstract
The utility model discloses a double control surge protector, comprising a housing, and a pressure-sensitive resistor, a fuse link welded with the pressure-sensitive resistor through low melting point alloys and a control elastic sheet arranged in the housing. The inner of the housing is also provided with a temperature-sensitive helical disk and a control lever; a control separating eccentric gear is arranged between the pressure-sensitive resistor and the fuse link. The housing is provided with a rotating shaft; the control separating eccentric gear is arranged on the rotating shaft and is provided with a V-shaped projection. The double control surge protector has a simple structure and realizes double control including the control by the control elastic sheet and the control by the combination of the temperature-sensitive helical disk and the control separating eccentric gear, which effectively guarantees control timeliness and validity to some extent and meanwhile guarantees control stability; the double control surge protector has the characteristics of high use security and reliability, strong applicability and good reliability and widens a use scope to some extent.
Description
Technical field
The utility model belongs to surge protection technical field, is specifically related to a kind of double-cotrolled type surge protector.
Background technology
Extensive use along with electrical equipment, electrical equipment damage in order to prevent that thunder and lightning from causing in electrical equipment use procedure, generally on electrical equipment, all lightning surge protector can be installed, the surge protector of prior art is generally by housing, piezo-resistance, elastomeric element forms, it is realized deenergization and then reaches thunder and lightning overvoltage protection with the separated of piezo-resistance by elastomeric element, although it is lightning protected that it can be realized to a certain extent, yet its stability in use is poor, while using long time, also easily make the elastic force of elastomeric element weaken, affect the normal use of surge protector, applicability is poor.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, the double-cotrolled type surge protector that stability in use is good and applicability is strong.
The technical scheme that realizes the utility model object is a kind of double-cotrolled type surge protector, comprise housing, be arranged on the piezo-resistance in described housing, fuse link with piezo-resistance activity butt, be arranged on the described piezo-resistance of the control control shell fragment separated with fuse link in described housing, the movable butt setting of described control shell fragment and described fuse link, in described housing, be also provided with temperature-sensitive helical disk and control lever, between described piezo-resistance and described fuse link, be provided with and control separated eccentric wheel, on described housing, be provided with rotating shaft, the separated eccentric wheel of described control rotates and is arranged in described rotating shaft, on the separated eccentric wheel of described control, be provided with into the projection that V-shape arranges, an end points of described control lever is fixed on housing, another end points is connected with the separated eccentric wheel of described control, and the middle part of described control lever is connected with the outer end points of described temperature-sensitive helical disk, two end points places that control lever is being controlled separated eccentric tie point and V-shape and raised into straight line and be separately positioned on straight line, described control lever is under the expansion of described temperature-sensitive helical disk drives, the end points being fixed on housing of take is turning point, another end points drive control separated eccentric wheel centered by rotating shaft, rotate and make V-shape projection respectively butt piezo-resistance with on fuse link, make piezo-resistance separated with fuse link.
The separated eccentric wheel of described control is insulating ceramics eccentric wheel.
Described fuse link is by leaving space between multi-layer thin copper sheet stack combinations and multi-layer thin copper sheet.
Described control shell fragment is arc setting.
The utlity model has positive effect: of the present utility model simple in structure, it not only has the shell fragment of control and controls, also there is temperature-sensitive helical disk simultaneously and control with controlling separated eccentric wheel combination, realize dual control object, effectively guaranteed to a certain extent promptness and the validity controlled, also guaranteed the stability of controlling simultaneously, safety in utilization is good, and reliability is high, has improved to a certain extent its scope of application, applicability is strong, and practicality is good.
Accompanying drawing explanation
