Problems solved by technology
[0004] The object of the present invention is to provide an electric leakage protection switch for electrical instrument automation, to solve the problem of Because it does not have an anti-leakage protection structure, the staff are easily injured when they are working, which increases the risk factor of the staff when they are working. At the same time, because of the high uncertainty of leakage, it will increase the use of equipment. At the same time, the existing anti-leakage structure mostly adds an insulating layer on the outside of the switch to reduce the risk of electric shock, but when the switch is installed, it occupies a large area, which will affect the scope of application of the switch. And most of the switches are made of insulating materials, the protection effect is not enough, and when the switch is in use, there is no monitoring structure for the electric shock of the connector, which cannot help the maintenance personnel to work, which affects the work efficiency

Abstract
An electric instrument automation anti-creeping protection switch disclosed by the present invention comprises a switch body, the outer side of the switch body is detachably connected with an anti-creeping protection sleeve, the outer side of the anti-creeping protection sleeve is fixedly provided with a transparent window, and the anti-creeping protection sleeve is provided with a positioning installation groove. A wire connecting groove is formed in the switch body, a voltage detector is movably installed on the switch body, a display screen is fixedly installed on the voltage detector, an auxiliary positioning block is fixedly installed at the lower end of the voltage detector, and an insulating sleeving seat is fixedly installed at the lower end of the auxiliary positioning block. An installation connection groove is formed in the insulation sleeve connection seat, a connection installation hole is reserved in the installation connection groove, and a contact probe is fixedly installed in the connection installation hole. According to the automatic anti-creeping protection switch for the electrical instrument, the detachable anti-creeping protection sleeve is additionally arranged on the outer side of the switch, so that the switch can be better installed and fixed, and the possibility of electric shock of maintenance personnel is reduced.
Description
technical field [0001] The invention relates to the technical field of electrical instruments, in particular to an automatic leakage protection switch for electrical instruments. Background technique [0002] Power meters are power measurement and control equipment that provide solutions for power parameter measurement, power quality monitoring and analysis, and electrical equipment control. Functions such as maximum value recording and event sequence recording can realize monitoring, remote control and alarm output of field equipment status through I / O modules, and can realize online power quality analysis, total harmonic distortion rate of each phase voltage and current, The content of odd harmonics, voltage and current unbalance, crest factor, telephone harmonic form factor, and K factor can be measured in real time. [0003] However, when the existing electrical switch is in use, because it does not have an anti-leakage protection structure, the staff is easily injured ...
