Insulation detection device and method for high-voltage direct-current power supply system

Abstract

The invention discloses an insulation detection device for a high-voltage direct-current power supply system. The insulation detection device comprises a base, wherein moving wheels are arranged on two sides of the base; a charging jack is formed in the side surface, bearing seats are fixed on two sides of the front and rear ends of the interior through screws, a rotating shaft of each moving wheel is arranged in the interior of the corresponding bearing seat in a sleeving manner, an inner fixed mount is arranged at the center of the interior of the base, a storage battery is arranged at the upper part of the inner fixed mount, the storage battery is electrically connected with the charging jack, a heat dissipator is arranged at the bottom of the storage battery, and ventilation holes areformed in the bottom of the heat dissipator; a detection device is arranged on one side of the inner fixed mount, and automatic winders are arranged on two sides of the detection device; a groove in the front end of the base is internally provided with a connector lug, a hole for a wire to pass through in the front end of the base is internally provided with a wear-proof sleeve, a wire outgoing sleeve is arranged at the upper end of the rear side of the base, an upright post is arranged at the upper end of the wire outgoing sleeve, and a control box is fixed at the top of the upright post through screws. According to the insulation detection device, intelligent detection can be carried out on the power supply system, so that the detection efficiency is high, data statistics are convenient,and the working strength is reduced.

Description

technical field [0001] The invention relates to the technical field of power monitoring devices, in particular to an insulation detection device and method for a high-voltage direct current power supply system. Background technique [0002] High-voltage DC power supply is a high-power long-distance DC transmission that uses stable DC power with no inductive reactance, capacitive reactance does not work, and no synchronization problems. The advantage is that without increasing the short-circuit capacity of the system, it is convenient to realize the non-synchronous network operation of the two power systems and the network connection of power systems with different frequencies; the use of power modulation of the DC system can improve the damping of the power system, suppress low-frequency oscillations, and improve AC transmission in parallel operation. power transmission capacity of the line. In order to ensure safety, the high-voltage DC power supply system generally suspen...

AI Technical Summary

Problems solved by technology

In order to ensure safety, the high-voltage DC power supply system generally suspends the cables or lays them in a confined space. However, due to the large power supply range of the power supply system, it is difficult to understand the situation during the power transmission process. When a human body touches the power supply during the power transmission process It is easy to be dangerous when connecting the line, so it is necessary to regularly check the insulation of the line

In the existing technology, the device for automatic detection of the insulation resi
