Background

For a long time, connectors for instrument verification, micro-water measurement, gas supplement and decomposition product test of SF6 operation have no unified size standard, equipment manufacturers are numerous, the structures and the connections of the connectors are various and fancy, the connectors are very unfavorable for field operation, and the connectors are mainly embodied in the following aspects:

1. the preparation, transportation and management of the SF6 joint are inconvenient. 4 sleeve joints are needed, even 8 sleeve joints and 12 sleeve joints are needed, the joints of various manufacturers are easy to misplace and misplace, disorder and loss are caused, and the work cannot be normally carried out sometimes due to the wrong joints.

2. During operation, due to different work of instrument verification, micro-water measurement and decomposition product testing, the joints need to be frequently replaced, SF6 gas in the equipment is wasted, the surrounding environment is polluted, meanwhile, an SF6 connecting port of the circuit breaker equipment is easily damaged, and the risk of operation accidents caused by SF6 leakage is high.

3. The connector is required to be frequently replaced according to different operation contents during operation, and the problems that operators repeatedly lift and lower insulators, repeatedly disassemble and assemble the connector and repeatedly jack open the sealing valve of the circuit breaker exist in the process. These factors reduce the working efficiency of the operator, increase the risk of damaging the sealing valve and waste of SF6 gas.

We find through research and analysis that the above operations have one thing in common: it is necessary to jack open the circuit breaker seal valve and then test using the plumbing test equipment. Furthermore, a design concept that one set of valve circuit is matched with four sets of test hosts is developed, the requirement of quick connection and universal performance is considered, and the quick connection and universal multi-way valve for SF6 operation is finally designed and manufactured.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, the size data of sealing valves of various types of circuit breakers are measured in a field statistics mode, and a quick-connection multi-way valve for SF6 operation is provided for four sets of testing equipment interfaces, and the technical scheme is as follows:

the utility model provides a fast even multiple unit valve for SF6 operation, is including locating the first joint of box one side and locating a plurality of joints of box opposite side, and first joint communicates with a plurality of joints of opposite side, first joint and main line intercommunication, and the main line communicates with the branch pipeline of a plurality of joints of opposite side respectively, and is equipped with the valve on main line and the branch pipeline.

Further, the box opposite side is equipped with 5 and connects, and all connect and be the contrary joint that ends of inserting fast, and the number, the size and the specification that connect can change as required.

Furthermore, all valves are spherical valves, the spherical valves are arranged on pipelines inside the box body, and operating handles of the spherical valves are arranged on the surface of the box body.

Further, the first joint is connected with a sealing valve of the circuit breaker, and the joint at the other side of the box body is sequentially connected with an SF6 decomposition product testing device, a micro-water measuring device, a gas filling device and an instrument checking device.

Further, one of the connectors on the other side of the box is used for configuring a standard connector M20 multiplied by 1.5 and matching a transit connector for connecting equipment with special size.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model discloses can replace 4 sets of device's nearly 150 joints before, it is very convenient to manage, transport, use. The connection is carried out once during operation, multiple SF6 test devices are replaced or shared simultaneously, damage to a sealing valve connector of the SF6 circuit breaker due to frequent replacement of connectors is avoided, operation risks are reduced, and working efficiency is greatly improved. The effect is very obvious, and the application frequency and the application prospect are very wide.
