Abstract
The utility model relates to an explosion-proof capacitor housing comprising a housing body, a capacitor unit disposed in the housing body, and pins disposed on the housing body. A cross section of the top part of the housing body is in a semicircular shape. A cross section of the bottom part of the housing body is in a rectangular shape. A buffer layer is disposed on the inner surface of the housing body. An explosion-proof layer is disposed on the inner surface of the buffer layer. The buffer layer is tightly pasted on the explosion-proof layer. Because the explosion-proof layer and the buffer layer are disposed, if the temperature in the capacitor is over high, the buffer layer may effectively relieve pressure generated when the capacitor is expanded in order to prevent explosion caused by over high temperature.
Description
Technical field
The utility model relates to a kind of anti-explosion capacitor housing.
Background technology
In DC circuit, capacitor is equivalent to open circuit.Capacitor is a kind of element that can store electric charge, is also one of the most frequently used electronic component.Capacitor of the prior art is mainly comprised of housing, conducting strip, fuse and filler.
Capacitor is widely used as compensating power in electric power system, and capacitor arrangement is originally that three-phase capacitor unit is fixing together, is enclosed in casing.When electrical equipment is long between in use, can make condenser current strengthen, temperature raises, and the material of capacitor internal expands rapidly and causes capacitor blast, is therefore necessary capacitor to do Explosion-proof Design.
Utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of anti-explosion capacitor housing is provided.
The utility model is to be achieved through the following technical solutions:
A kind of anti-explosion capacitor housing, comprise that housing, described housing are built-in with capacitor cell and are located at the pin on housing, the upper end section semicircular in shape of described housing, lower end section is rectangle, described shell inner surface is provided with resilient coating, and the inner surface of described resilient coating is provided with explosion-proof layer.
Further, the thickness of described resilient coating is 3-8mm.
Further, described explosion-proof layer is 4-10mm.
Further, described resilient coating and explosion-proof layer closely glue together.
Compared with prior art, the beneficial effects of the utility model are: the utility model is by explosion-proof layer and resilient coating are set, and in capacitor, during excess Temperature, resilient coating can effectively be alleviated the pressure producing while expanding, and avoids excess Temperature to produce blast.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of anti-explosion capacitor housing, comprise that housing 1, described housing 1 are built-in with capacitor cell 2 and are located at the pin 3 on housing 1, the upper end section semicircular in shape of described housing 1, lower end section is rectangle, described housing 1 inner surface is provided with resilient coating 4, and the inner surface of described resilient coating 4 is provided with explosion-proof layer 5, and described resilient coating 4 closely glues together with explosion-proof layer 5, the thickness of described resilient coating 4 is 3-8mm, and described explosion-proof layer 5 is 4-10mm.
To sum up, the utility model is by explosion-proof layer 5 and resilient coating 4 are set, and in capacitor, during excess Temperature, resilient coating 4 can effectively be alleviated the pressure producing while expanding, and avoids excess Temperature to produce blast.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
