Abstract
The utility model provides an interface device used in an electrified humidity test of sulfur hexafluoride gas of electrical equipment. The interface device is provided with a joint, a top head is arranged at the middle of the joint, the top head is fixed at the joint through a supporting rod, the joint and the inlet end of a stop valve are installed together, and the outlet end of the stop valve is provided with an outlet pipe. The interface device is capable of realizing the electrified humidity test of sulfur hexafluoride gas. The interface device has advantages of convenience in use and safety. The interface device can efficiently prevent the leakage of gas when the stop valve is in fault. Testing time can be chosen freely to meet the requirement of testing period, and the problem that the electrical equipment insulated by sulfur hexafluoride gas can not be defected in tracking mode in working process is solved. The veracity of a test result is improved, so timely and reliable state information is provided for state maintenance.
Description
Technical field
The utility model provides a kind of electrical production to use device, the interface arrangement of sulfur hexafluoride gas humidity in especially a kind of detecting electric equipment.
Background technology
For guaranteeing to utilize electrical equipment that sulfur hexafluoride gas insulate, need test the humidity of sulfur hexafluoride gas such as the converting equipment safe operation.At present, this test is normally carried out under the power failure condition.But in real work, be unpractical for test gas humidity has a power failure equipment only, this just causes the ultra sense cycle operation of large quantities of converting equipments that utilize sulfur hexafluoride gas to insulate.Have a power failure even have an opportunity, power failure also not necessarily meets the requirement of test period opportunity.At present, there is certain security risk in charged detection sulfur hexafluoride gas appropriateness.Its reason is: utilize the gas detection mouth on the electrical equipment that sulfur hexafluoride gas insulate to be controlled by a reverse checkvalve, when moving at ordinary times, the pressure of device interior is closed reverse checkvalve automatically, and gas can not flow out.Inflating or gas humidity when detecting, make reverse checkvalve open, gas can flow out or flow into.Behind the end-of-job, reverse checkvalve is closed under the internal pressure effect at once.If reverse checkvalve breaks down, can not close, gas can leak, and gas leaks into to a certain degree, and device interior can cause fault to take place because of dielectric level descends.
Summary of the invention
The utility model technical matters to be solved is the interface arrangement of sulfur hexafluoride gas humidity in a kind of live testing electrical equipment to be provided, to improve the convenience and the security of test.
The utility model is achieved in that the interface arrangement of sulfur hexafluoride gas humidity in the live testing electrical equipment, and it has joint; There is the top at the joint middle part; The top is fixed on the joint through support bar, and joint and stop valve inlet side are installed together, and stop valve goes out on the end has the pipe of going out.
Adopt the interface arrangement of said structure, can realize the humidity of live testing sulfur hexafluoride gas, easy to use, safe, gas leaks can effectively to prevent reverse checkvalve to break down afterwards.Can freely select test opportunity, make its requirement that meets test period, solve the electrical equipment that utilizes sulfur hexafluoride gas to insulate can not be followed the tracks of detection in operational process a difficult problem.Improved the accuracy of testing result, for repair based on condition of component provides in time status information reliably.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model structure.
Embodiment
The embodiment that provides below in conjunction with accompanying drawing further specifies the utility model.
Shown in accompanying drawing, the interface arrangement of sulfur hexafluoride gas humidity in the live testing electrical equipment of the utility model, it has joint 2; There is top 6 at the joint middle part; The top is fixed on the joint through support bar 5, and joint and stop valve 7 inlet sides are installed together, and stop valve goes out on the end has the pipe of going out 8.
When needing the humidity of sulfur hexafluoride gas in the live testing electrical equipment 1; Joint is installed on the reverse checkvalve 3 that connects on the electrical equipment 1; Withstand on the thimble 4 on the reverse checkvalve; Reverse checkvalve is opened, and the sulfur hexafluoride gas in the electrical equipment gets into out pipe 8 through reverse checkvalve, joint inner chamber, stop valve, is connected on out the humidity that testing apparatus on the pipe can detect sulfur hexafluoride gas.After test finishes,, can not close, can close stop valve, this interface arrangement is retained on the reverse checkvalve always, leak to prevent sulfur hexafluoride gas if reverse checkvalve breaks down.Change problematic reverse checkvalve when treating the equipment interruption maintenance again.
