Problems solved by technology

[0002] During the on-site power inspection process of substation power outages, there are the following problems: first, the operation and maintenance personnel need to carry four kinds of electroscopes with different voltage levels during switching operations, and it is easy to miss and forget to check that the electroscopes are good, which delays the operation time; There are many types of on-site electroscopes, and it is easy to get the wrong voltage level during the electroscope, resulting in misoperation; third, the management of electroscopes is complicated, inconvenient to carry and use, and high maintenance costs. question
However, at present, the operation and maintenance personnel of power substation still use the traditional electric inspection method when carrying out electric inspection on the spot of power outage operation, and carry electric detectors with multiple voltage levels. Improve operational safety

Abstract

The invention discloses a multi-voltage-grade optional electroscope, which comprises: a detection probe, which internally comprises a starting circuit, an oscillating circuit, a sound-light alarm circuit, and a self-checking circuit; an indicator, the surface of which is fixedly equipped with an experiment button, an LED display screen, an alarm indicating lamp and a voltage change-over switch; atelescopic insulating rod; and a rubber handle; wherein one end of the detection probe is fixedly connected with the indicator, one side of the indicator is fixedly connected with the telescopic insulating rod, and one end of the telescopic insulating rod is fixedly connected with the rubber handle. The multi-voltage-grade optional electroscope is simple in structure, convenient to carry and use,low in cost and high in efficiency; operation and maintenance personnel only need to carry one electroscope on site to meet the electricity testing requirements of all voltage grades.

Description

technical field [0001] The invention relates to the technical field of high voltage electroscope for power transformation operation and maintenance, in particular to an electroscope with multiple voltage levels selectable. Background technique [0002] During the on-site power inspection process of substation power outages, there are the following problems: first, the operation and maintenance personnel need to carry four kinds of electroscopes with different voltage levels during switching operations, and it is easy to miss and forget to check that the electroscopes are good, which delays the operation time; There are many types of on-site electroscopes, and it is easy to get the wrong voltage level during the electroscope, resulting in misoperation; third, the management of electroscopes is complicated, inconvenient to carry and use, and high maintenance costs. question. However, at present, the operation and maintenance personnel of power substation still use the traditi...
