Full-voltage full-loop self-checking capacitive-type electroscope

Abstract

The invention discloses a full-voltage full-loop self-checking capacitive-type electroscope which comprises an electroscope circuit box, an insulating operation bar and a handle. The electroscope circuit box is provided with a checking probe and a display screen and comprises a micro-controller module and a self-checking circuit module. The electroscope circuit box is internally provided with a voltage-level conversion circuit box and a voice broadcasting module. An input end of the voltage-level conversion circuit box is connected with the checking probe while an output end of the same is connected with the micro-controller module. The input end of the voltage-level conversion circuit box is further connected with the self-checking circuit module through the checking probe, and the voice broadcasting module is connected with the micro-controller module. Therefore, full voltage switching can be realized through the full-voltage full-loop self-checking capacitive-type electroscope. Meanwhile, the electroscope can perform self-checking and broadcast voltage classes selected by operating personnel who are reminded to perform secondary confirmation, so that accident occurrence due to the fact that unmatched voltage classes are selected for checking electricity by the operating personnel can be effectively avoided.

Description

technical field [0001] The invention relates to an electroscope, in particular to a full-voltage full-loop self-test capacitance type electroscope. Background technique [0002] In accordance with the requirements of the "State Grid Corporation Electricity Safety Work Regulations", when conducting electrical inspections, qualified contact electroscopes with corresponding voltage levels should be used. The scope of use of the electroscope is 6KV, 10 KV, 35 KV, 110 KV, 220 KV, 330 KV, 500 KV and other AC voltages. At present, although the contact electroscope used in the electric inspection of substation and line work has realized the functions of full-circuit self-inspection, sound and light alarm, etc., and when it is impossible to test on the electric equipment, the power frequency high-voltage generator can be used for confirmation inspection. Whether the electrical appliance is in good condition, but it does not have the function of full voltage switching during on-site ...

Problems solved by technology

At present, although the contact electroscope used in the electric inspection of substation and line work has realized the functions of full-circuit self-inspection, sound and light alarm, etc., and when it is impossible to test on the electric equipment, the power frequency high-voltage generator can be used for confirmation inspection. Whether the electrical appliance is in good condition, but it does not have the function of full voltage switching during on-site electrical inspection

However, in actual work, it is often necessary to measure a variety of circuits with different voltage levels, which leads to the need for staff to carry a variety of measurement tools during substation and line operations, which is very inconvenient to carry.

At the same time, every time a circuit with a different voltage level is measured, it is necessary to replace the measurement tool of the corresponding level, which also brings inconvenience to the operation of the staff.
