Abstract
The utility model discloses a kind of ring main unit explosion-proof control system, comprise cabinet, pressure transducer, controller, blowdown valve, valve control mechanism and pressure release window; Cabinet is provided with pressure release window; Described blowdown valve is arranged at pressure release window place; Described pressure transducer, controller, valve control mechanism are connected successively with blowdown valve; Described valve control mechanism is for controlling the opening and closing of blowdown valve.The utility model adopts setting pressure sensor in cabinet to detect the air pressure in cabinet, reaches predetermined threshold value once cabinet air pressure, carrys out pressure release by starting blowdown valve; Thus eliminate electrical equipment explosion danger.The pressure data of ring main unit is transferred to server to store, to understand the history duty of ring main unit simultaneously.
Description
Technical field
The utility model relates to high voltage electric equipment security technology area, especially relates to a kind of ring main unit anti-explosion safety detection system.
Background technology
The Inflatable ring main unit explosion relief valve used in the market is membrane type structure, produces arcing, make the temperature inside the box and the hurried rising of pressure, easily produce explosion phenomenon when casing internal short-circuit or big current disjunction; Likely cause casualty accident, therefore, need a kind of device that can carry out explosion-proof control to ring main unit.
Utility model content
For the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of ring main unit explosion-proof control system.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of ring main unit explosion-proof control system that the utility model provides, comprises cabinet, pressure transducer, controller, blowdown valve, valve control mechanism and pressure release window;
Described cabinet is provided with pressure release window; Described blowdown valve is arranged at pressure release window place; Described pressure transducer, controller, valve control mechanism are connected successively with blowdown valve; Described valve control mechanism is for controlling the opening and closing of blowdown valve.
Further, described pressure transducer is arranged on fixed support, and described fixed support is arranged on cabinet; Described fixed support comprises location division and fixed part; Described location division is arranged on casing; Described location division forms outstanding annulus in fixed part side; Described annulus arranges pressure transducer; Described fixed part arranges controller.
Further, LAN switch and background server is also comprised; Described controller is connected with background server by LAN switch.
Further, also comprise alarm module, described alarm module is connected with controller.
Further, described controller is single-chip microcomputer.
Adopt after said structure, the utility model compared to the prior art advantageously:
The utility model adopts setting pressure sensor in cabinet to detect the air pressure in cabinet, reaches predetermined threshold value once cabinet air pressure, carrys out pressure release by starting blowdown valve; Thus eliminate electrical equipment explosion danger.The pressure data of ring main unit is transferred to server to store, to understand the history duty of ring main unit simultaneously.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is ring main unit explosion-proof control system schematic diagram of the present utility model.
