Problems solved by technology

[0004] However, since the leakage current sensor in the prior art is connected in series with the insulator, the current flowing through the leakage current sensor is the same as the leakage current of the insulator, and the leakage current of the insulator can be obtained directly. Therefore, the monitoring circuit is not isolated from the leakage current. There is a problem with current leakage

Abstract

The invention provides a leakage detection device and an insulator leakage detection device, system and method. A through-hole leakage detection device is used to acquire leakage current in a non-contact manner. Leakage current can be sensed without arranging the device on an insulator. The device is hooped on insulator hardware to be applied to insulators of a variety of specifications. A solar battery and a rechargeable battery are used for power supply together, which effectively increases the service life of the device. The Internet of Things is used for networking, and the leakage current state of insulators in a region can be effectively collected, and data are transmitted to a monitoring center through the Internet of Things communication technology. According to the invention, the problem of current leakage is effectively solved; the devices are simple to install and suitable for mass production, and have long running time; the devices run in an equipotential environment, which reduces electromagnetic interference; and electrical insulation is improved through an insulation gasket and an insulation sleeve.

Description

technical field [0001] The invention relates to the field of high-voltage transmission line detection and the field of the Internet of Things, in particular to a leakage detection device, an insulator leakage detection device, a system and a method. Background technique [0002] The pollution flashover of power transmission equipment seriously threatens the safety of the power system and brings great harm to the normal operation of the power grid. Among them, the pollution flashover of insulators has become the number one killer that threatens the operation of the power system. As a device widely used in transmission lines, insulators are placed outside for a long time and are easily affected by harsh weather and environmental pollution. Insulators that have been operating in these environments for a long time will form a dirty layer on the outer surface. When the dirty layer is excessively accumulated, the surface of the insulator will Contamination will become moist and de...
