Cover board both sides are connected with several connecting rods, and described connecting rod one end is connected with fixture block, and the fixture block is arranged on sliding rail, described to let out
The other both sides of cover clamp are connected with several connecting plates, are connect with mounting plate by several springs below the connecting plate.
As a kind of optimal technical scheme of the utility model, several pressure relief vents are provided on the pressure release cover board, it is described
Shell is fixedly connected with threaded post, and the shell passes through threaded post and the removable connection of threaded hole.
As a kind of optimal technical scheme of the utility model, the sliding rail is fixedly mounted on shell both sides, the connection
Bar is moved freely by fixture block on sliding rail.
As a kind of optimal technical scheme of the utility model, the shell is hollow structure, is arranged on the mounting plate
There are several grooves, the size of the groove to be less than the cross sectional dimensions of shell.
As a kind of optimal technical scheme of the utility model, several screws are provided on the mounting plate.
The advantageous effect that the utility model is reached is：This circuit breaker type ring main unit pressure relief device is by being provided with release
Hole enables to ring main unit air pressure inside to obtain certain release, and when air pressure inside is excessively high, air-flow is flowed out by pressure relief vent,
Since pressure release cover board can be moved freely by connecting rod and fixture block on sliding rail, so air-flow can drive pressure release cover board to move up,
So that pressure release cover board leaves shell, ring main unit internal high pressure can be discharged, after ring main unit air pressure inside is released, cover board exists
Under the action of spring, moved down by connecting plate drive, lid on the shell, by being provided with mounting plate and screw, enables to this dress
It sets and is easily installed, shell is connect by threaded post and threaded hole with mounting plate so that the present apparatus is easily installed and dismantles, more just
Just it repairs.
