Description
Technical field
The utility model relates to a kind of rupture pressure disc mounting cover, specifically a kind of new type explosion proof film mounting cover.
Background technology
Gas insulation metal seal combined electrical apparatus is made up of circuit breaker, isolating switch, earthed switch, instrument transformer, lightning rod, bus, connector and outlet terminal etc., these equipment or parts are all enclosed in the shell of metallic ground, be filled with the six-component force balance gas of certain pressure therein, the English abbreviation of gas insulation metal seal combined electrical apparatus is GIS.
The each functional unit of GIS has independent air chamber, and the air pressure in air chamber reaches 0.5-0.6MPa.In order to ensure the fail safe of GIS, air chamber needs to arrange rupture pressure disc, especially circuit breaker air chamber.The effect of rupture pressure disc is exactly be the sudden change preventing gas gas pressure inside, the means for guiding gas above rupture pressure disc, ensure that rupture pressure disc is when opening, and gas sprays to a direction limited and can not hurt operations staff.
Gas insulation metal seal combined electrical apparatus is inner in circuit breaker assembling, and the setting of rupture pressure disc is absolutely necessary! And in the application of reality, in the transformer station in particularly coastal cities, moisture is large and rainwater is many, rupture pressure disc is easily in the environment of water, affects the security performance of substation equipment.
Utility model content
The purpose of this utility model is to provide a kind of new type explosion proof film mounting cover, can solve the problem.
The utility model for achieving the above object, be achieved through the following technical solutions: a kind of new type explosion proof film mounting cover, comprise device housings, device housings offers through hole, seamless pipe holder is installed on the top of device housings, seamless pipe is installed on the top of seamless pipe holder, the inside of seamless pipe communicates with through hole, the upper bend of seamless pipe, the upper orifice of seamless pipe vertically down, seamless pipe is inverted J-shaped, the upper orifice of seamless pipe installs plastic closure, rupture pressure disc holder is installed in the bottom of device housings, holddown groove is offered at the middle part of rupture pressure disc holder, rupture pressure disc is installed in holddown groove inside, rupture pressure disc is arcwall face structure, the direction of rupture pressure disc arc is downward, rupture pressure disc can cover the lower end of through hole.
In order to realize the purpose of this utility model further, can also by the following technical solutions: the first cannelure is offered in the bottom of described seamless pipe holder, and the first sealing ring is installed in the inside of the first cannelure, the first sealing ring is positioned at the side week of through hole.The second cannelure is offered in the bottom of described device housings, and the first annular slot is in the side of through hole week, and install the second sealing ring in the first cannelure, the second sealing ring is between device housings and rupture pressure disc holder.
The utility model has the advantage of: the seamless pipe of the utility model in circuit breaker assembling arranges plastic closure, what plastic closure can prevent moisture and rainwater enters circuit breaker, thus ensure that GIS safe operation, is also beneficial to the stable operation of transformer station.The upper bend of seamless pipe of the present utility model, vertically down, seamless pipe is inverted J-shaped for the upper orifice of seamless pipe, when such design can make rupture pressure disc cracked pressure release, the fragment of rupture pressure disc can directly be got on device housings, thus avoids the debris damage of rupture pressure disc to neighbouring personnel.Rupture pressure disc of the present utility model is arcwall face structure, and the direction of rupture pressure disc arc is downward, and rupture pressure disc can be avoided chipping under less pressure.The utility model also has advantage compact, cheap for manufacturing cost and easy to use simple for structure.
