The SF6 gas density relay is one of the key elements of the SF6 electrical switch, is used for detecting the change of the SF6 gas density in the SF6 electrical equipment body, and the performance of the SF6 gas density relay directly influences the reliable and safe operation of the SF6 electrical equipment. The SF6 gas density relay installed on the site does not operate frequently, and after a period of time, the phenomenon of inflexible operation or poor contact of contacts often occurs, and some of them also have poor temperature compensation performance, and when the environmental temperature changes, the SF6 gas density relay is easy to malfunction. "preventive test procedure for electric Power Equipment" this test procedure stipulates: each SF6 electrical switch unit of use should regularly verify the SF6 gas density relay. From the actual operation condition, the regular verification of the SF6 gas density relay on site is one of the necessary means for preventing the trouble and ensuring the safe and reliable operation of the power equipment. Therefore, the test is very important.

At present, in the SF6 density relay test, because the secondary junction box is too small, the needle type outgoing line led out from the meter head is very small, and the distance between the needle and the needle does not meet the wiring, the secondary line is often connected with a meter for testing during the test, and when the secondary line wiring fault exists, the fault is misjudged as the density relay fault.

Therefore, a test wire connector applied to an SF6 density relay is needed, a wire clamping test can be directly performed on an SF6 density relay meter head, meanwhile, the conduction of a secondary wire can be measured, and the risk that a density relay meter junction box is too small, and the direct measurement and misjudgment of the wiring cannot be performed is solved.
