Description
Technical field
The utility model belongs to micro- water density monitoring device field, more specifically to a kind of SF6 gas in line generalization
Monitoring device.
Background technique
Current SF6 gas be widely used in its superior insulation, arc extinction performance power industry high-voltage circuitbreaker and
In transformer equipment, since SF6 gas moisture is exceeded or density decline all can constitute grave danger to the safe operation of electrical equipment,
Its decomposition product has severe toxicity, once leakage will cause very big injury to operator, it is therefore necessary to using the conduct of SF6 gas
Insulation, arc-extinguishing medium electrical equipment in SF6 gas carry out the detection of regularly moisture, density.
Its placement gas sensor of existing tester can only generally measure a kind of parameter of SF6 gas, gas chamber and sensing
Only with a kind of sealing means between device, therefore not only measurement is inconvenient, is easy to appear gas leakage during installation and draws
Play great electric power safety accident.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of SF6 gases in line generalization
Monitoring device, design rationally, micro- water of SF6, density, temperature are merged and measured in a gas chamber, and sealing means
It is safer, toxic gas will not be revealed, effect is improved, wiring is simple and convenient, improves monitoring reliability of operation, safety
Property and validity, be suitable for promote.
To achieve the above object, the utility model provides following technical solution:
A kind of online composite monitoring device of SF6 gas, it is characterised in that: including main air chamber, the company positioned at main air chamber both ends
Connector and reserved gas supplementing opening, connector and reserved gas supplementing opening and main air chamber use dual-seal, are provided with several biographies in main air chamber
Sensor, the top of main air chamber are provided with circuit board, and circuit board is responsible for for sensor signal being converted into digital signal, then by communication core
Piece sends out digital signal, and circuit board upper end is connecting terminal；Connecting terminal is connected with communication line, and communication line is by transmitter
Lid penetrates, and connect with connecting terminal, finally tightens the waterproof connector above transmitter covers, plays sealing effect.
As a kind of technical solution of optimization, the sensor includes SF6 gas purity sensor, micro- water density sensing
Device, temperature sensor and SO 2 sensor.
As a kind of technical solution of optimization, the number of the circuit board is 2-4 block.
As a kind of technical solution of optimization, thread seal and flat seal are provided between the connector and main air chamber
Dual-seal；The dual-seal of thread seal and flat seal is provided between the reserved gas supplementing opening and main air chamber.
By adopting the above-described technical solution, compared with prior art, the utility model is designed reasonably, by micro- water of SF6,
Density, temperature merging measure in a gas chamber, and sealing means are safer, will not reveal toxic gas, improve
Effect, wiring is simple and convenient, improves monitoring reliability of operation, safety and validity, is suitable for promoting.
The utility model is described further referring to drawings and examples.
