Description
Technical field
The present invention relates to field transformer, specially a kind of mine oil immersed type explosion-proof transformer.
Background technology
Oil-filled transformer is comparing safety and a kind of transformer for being commonly used, oil-filled transformer in the process of running internal fault such as flashover, climb the phenomenons such as electricity or short circuit and happen occasionally, easily cause increasing rapidly for pressure in transformer-cabinet.For the anti-rapid expansion that phenomenon causes the accident here, generally use the rapid pressure release of pressure relief valve, pressure relief valve is arranged on the top of transformer, when people are near transformer equipment, the unexpected oil spout of pressure relief valve can constitute a threat to personal safety, while producing the waste and the pollution to surrounding environment of resource.
The existing oil-filled transformer used for mine inside, complex structure and unstable properties, once damage, maintenance is pretty troublesome, existing oil-filled transformer can not discharge because temperature is too high in time, and the gases at high pressure for producing, this is to cause certain threat using safety to transformer, especially in this job that requires special skills occasion of mine, once blast occurs will cause very big life and property loss.
The content of the invention
It is an object of the invention to provide a kind of mine oil immersed type explosion-proof transformer, to solve the problems, such as to be proposed in above-mentioned background technology.
To achieve the above object, the present invention provides following technical scheme：A kind of mine oil immersed type explosion-proof transformer,Including shell and chock plug,The inner chamber middle part of the shell is fixed with iron core,The left and right sides of the iron core is wound with first siding ring and second siding ring respectively,The top left and right sides of the shell corresponds to first siding ring respectively and second siding ring is provided with lead-in clamp and output wiring terminal,The lead-in clamp is electrically connected with first siding ring,The output wiring terminal is electrically connected with second siding ring,Bounce cylinder is provided with the top of the shell,The downside of the bounce cylinder connects with shell,The top of the bounce cylinder is provided with gas outlet,Check valve is connected with the inside of the gas outlet,The check valve includes spacing ring,The spacing ring is fixedly connected with the madial wall of gas outlet,The chock plug is located at the upside of spacing ring,The top of the chock plug is fixedly connected with spring,The spring is fixedly connected with support,The support is fixedly connected with the madial wall of gas outlet.
Preferably, the upper left side of the shell is equipped with communicating pipe with lower left side, and transparent oil level pipe is connected between communicating pipe described in two groups.
Preferably, it is connected with rubber blanket on the downside of the chock plug.
Compared with prior art, the beneficial effects of the invention are as follows：This mine oil immersed type explosion-proof transformer simple structure, by adding bounce cylinder structure, can be to inside transformer, the gases at high pressure for operationally being produced due to high temperature carry out temporary transient caching, when the pressure of cylinder interior reaches certain numerical value, chock plug top can be held, gas is discharged, avoid high pressure blast, cause to damage by adding check valve that the dust in the external world can be avoided to fall into inside transformer, by adding spacing ring, can be to the position restriction of chock plug, accomplish when pressure is smaller, stablize motionless, when pressure is excessive, open chock plug release pressure, reach the purpose that protection transformer avoids blast, generally speaking, simple structure of the present invention, easily disassemble and install, use safety, it is adapted to be promoted the use of inside mine.
