Abstract
The utility model discloses an automatic degassing device for a gas relay in the power industry, which consists of a casing, a solenoid valve, a push plate and an exhaust valve, wherein the solenoid valve is arranged in an inner cavity of the casing; the push plate is fixedly arranged on the casing by a positioning bolt and is contacted with the solenoid valve and the exhaust valve; the exhaust valve is connected with the gas relay; the solenoid valve pushes the push plate in an electrified state to rotate and push the exhaust valve to exhaust; a valve core on the exhaust valve is provided with a spring, thereby the valve core can automatically close a sealing surface when the solenoid valve does not work; the valve core is provided with a ventilation groove for bringing convenience to the flowing of gas; and a gas-passing groove is arranged on a movable push rod and is controlled by the solenoid valve, so that the gas is convenient for exhausting and the phenomenon that the traditional climbing operation is inconvenient is reduced.
Description
Technical field
The utility model relates to the device that power industry is carried out exhaust to the power transmission and transformation transformer, specifically a kind of Buchholz relay automatic air eliminator.
Background technology
Relevant by retrieval patent documentation does not retrieve the Buchholz relay automatic air eliminator identical with the utility model structure at present as yet.The transformer of power industry transformer station needed regularly the methane gas in the transformer to be discharged after operation a period of time.Because the structural reason Buchholz relay generally is installed on the high end position of transformer, and the existing general employing of using of Buchholz relay is manually exitted, regularly gas being discharged needs to adopt the mode of ascending a height just can finish, this has brought a lot of inconvenience to field operation, so be necessary existing gaseous emission mode is improved, with handled easily, reduce labor intensity.
Summary of the invention
The purpose of this utility model is that a kind of improvement on existing Buchholz relay basis will be provided, and has easy to operate, as to realize automation control Buchholz relay automatic air eliminator.
Technical characterictic of the present utility model is: considering that control is convenient, and be designed to the Buchholz relay automatic air eliminator be made up of housing, electromagnetically operated valve, slurcam, vent valve on the basis of compact conformation, be provided with electromagnetically operated valve in the inner chamber of housing; Slurcam is packed on the housing and with electromagnetically operated valve, vent valve by bolt and contacts; Described vent valve is connected with Buchholz relay; Electromagnetically operated valve must promote slurcam under the electricity condition, makes the slurcam rotation, promotes vent valve and carries out exhaust.
Described vent valve is made up of valve pipe, spring, spool, sealing ring, bonnet, movable push bar, and the valve pipe is connected with the outlet of Buchholz relay, and spool is arranged in the inner chamber of valve pipe, and spring housing is contained on the spool, and bonnet is rotatably connected on the valve pipe; Be provided with the sealing ring that seals mutually with bonnet in the end of valve pipe, on bonnet, be provided with movable push bar.
Spool in the described vent valve is provided with air channel on its periphery, its sealing surface seals mutually with the bonnet sealing surface of bonnet.
Bonnet in the described vent valve is provided with steam vent, bonnet sealing surface; Sealing surface on described bonnet sealing surface and the spool forms a pair of sealing.
Movable push bar in the described vent valve was provided with air drain.
During use, the vent valve of existing Buchholz relay is removed, and vent valve and the Buchholz relay in the Buchholz relay automatic air eliminator of the present utility model is connected and sealed, housing is packed on the connecting bolt of Buchholz relay.In the time need discharging to the gas in the transformer, then feed power supply, electromagnetically operated valve begins work and promotes slurcam to be rotated, and the movable push bar that slurcam rotation back promotes in the vent valve moves down.Under the effect of movable push bar, movable push bar promotes the sealing surface generation gap that spool moves down the sealing surface that makes spool and bonnet, this moment, the methane gas in the Buchholz relay flow through gap between the sealing surface by the air channel on the spool, and flow through the air drain of crossing in the movable push bar, discharge by the steam vent in the bonnet again.After gaseous emission finishes, disconnect power of electromagnetic valve, electromagnetically operated valve is not worked, this moment, the effect bottom spool at spring moved up, the sealing surface on the spool and the sealing surface of bonnet are sealed, promote movable push bar simultaneously and move up and promote slurcam and reset, thereby realized the automatic discharging process of gas.
The utility model has the advantages that; Because the spool on the vent valve is provided with spring, thereby make the spool can be automatically that sealing surface is airtight when electromagnetically operated valve is not worked; Because spool is provided with air channel, thereby make gas flow convenient; Owing on movable push bar, be provided with air drain, and adopt electromagnetically operated valve to control, thereby make the methane gas discharging convenient, reduced the inconvenient phenomenon of existing ascend operation; Since rational in infrastructure, compact, easy for installation, so very big practical and popularizing value is arranged.
