Abstract

The utility model relates to a novel capacitor provided with a temperature protecting structure. The novel capacitor provided with the temperature protecting structure includes an outer shell and two groups of built-in capacitors. The two groups of the built-in capacitors are installed on the upper side and the lower side in an inner cavity of the outer shell respectively. Filler is arranged between the upper group and the lower group of the built-in capacitors. A temperature protection unit provided with a temperature sensing switch is installed on a connection wire between a built-in discharge resistor and the built-in capacitors. The novel capacitor provided with the temperature protecting structure provided by the utility model has beneficial effects that by adding the temperature protection unit provided with the temperature sensing switch in the novel capacitor provided with the temperature protecting structure, the temperature sensing switch can be opened automatically when inner working temperature of the novel capacitor provided with the temperature protecting structure surpasses 45 DEG C, so that the novel capacitor provided with the temperature protecting structure can be prevented from keeping working and continuous temperature rise as well as fires caused by the temperature rise are avoided; and the temperature sensing switch returns to a normally-closed state when the temperature in the novel capacitor provided with the temperature protecting structure is reduced to 35 DEG C, so that damages caused by overheat of the novel capacitor provided with the temperature protecting structure can be avoided to the maximum degree and electricity utilization cost of a client can also be reduced without doubt.

Description

A kind of novel capacitor with temperature protection structure
Technical field
The utility model relates to a kind of capacitor, relates in particular to a kind of novel capacitor with temperature protection structure.
Background technology
Capacitor is a kind of element that can store electric charge, also is one of the most frequently used electronic component.The process of capacitor charging/discharging is free, form the electric field that changes between pole plate, and this electric field also is time dependent function.It is temperature transition electric weight that temperature sensor adopts the temperature variant rule of the various physical propertys of material, is the core of temperature measuring instrument, various in style.Can be divided into contact and contactless two big classes by metering system, be divided into thermal resistance and thermocouple two classes, correspondingly, develop acoustics temperature sensor, infrared sensor and microwave remote sensor in succession according to sensor material and electron component characteristic.In conjunction with the narration of above capacitor and temperature sensor, the inner temperature protective device that lacks of existing capacitor, this can cause capacitor to decay fast owing to excess temperature causes capacity, reduction of service life, increases client's electric cost.Therefore, at above aspect, need reasonably improve prior art.
The utility model content
At above defective, the utility model provides a kind of and improves useful life, help the novel capacitor with temperature protection structure that improves electrical safety and stability, can reduce client's electric cost, to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
A kind of novel capacitor with temperature protection structure comprises shell body, two groups of built-in capacitors, is positioned at the upper and lower both sides of shell body inner chamber one group of built-in capacitor is housed respectively, and every group of built-in capacitor all is made up of three electric capacity that have the terminals insulating case; Between upper and lower two groups of built-in capacitors, be provided with filler; one of them external terminal of described built-in capacitor connects a built-in discharge resistance, and the temperature protection unit that has temperature sensing switch is installed in the wiring between built-in discharge resistance and the built-in capacitor.
Cover plate is installed at described shell body top, is positioned at the cover plate top over cap is set;
Be positioned at the shell body both sides some mounting brackets are set respectively.
Beneficial effect with novel capacitor of temperature protection structure described in the utility model is: by setting up a temperature protection unit that has temperature sensing switch in capacitor inside (during this switch operate as normal, be normally off), when capacitor internal work temperature surpasses 45 ℃, the temperature sensing switch automatic disconnection, thereby avoid capacitor to work on, cause temperature constantly to rise, also can avoid because bigger electric fault or the electric accidents such as fire that temperature rises and causes; When being reduced to 35 ℃ as temperature in the capacitor, temperature sensing switch reverts to normally off, and capacitor is devoted oneself to work again, by this process, can farthest avoid capacitor because the damage that excess temperature causes can certainly reduce client's electric cost.
