An intelligent power supply and distribution system with continuous remote monitoring of low-voltage switchgear

Abstract

The invention relates to an intelligent power supply and distribution system with a continuous remote monitoring and low voltage switch cabinet and has properties of high safety and high automation degree. The intelligent power supply and distribution system comprises a switch cabinet, wherein a conventional monitoring device is arranged in the switch cabinet, the side of the switch cabinet is provided with an observation window, a first wire and a second wire are mounted inside the observation window, an electric maintenance vehicle is arranged in a power distribution room, a second processor, a HD shooting module, a microphone and a rotary contour scanner capable of detecting whether the position of the switch cabinet is correct are arranged on the electric maintenance vehicle, whether abus in the switch cabinet is displaced or the tightening torque of a wiring nut are further monitored, whether the surface of a contact of an air switch is clean can be monitored, whether an operating mechanism of the air switch is in the correct position can be monitored, daily maintenance of the switch cabinet is completely realized, and labor cost is saved. With the conventional monitoring device, automatic real-time monitoring of the switch cabinet can be realized, and safety is greatly improved.

Description

technical field [0001] The invention relates to the technical field of intelligent power supply and distribution, in particular to an intelligent power supply and distribution system with continuous remote monitoring low-voltage switchgear with wide monitoring range, high safety and high degree of automation. Background technique [0002] The switchgear is suitable for power users such as power plants, substations, factories, mines, and enterprises. It is generally composed of cabinets, busbars, air switches, and air switch operating mechanisms. The power from the switchgear is transmitted from the busbar to the input end of the switchgear. sent to the terminal load. The stable operation of switchgear is an important prerequisite to ensure the normal work of power users. [0003] In the prior art, the method for monitoring the status parameters of the switchgear is to install a microcomputer protection device on the switchgear. Specifically, the microcomputer protection dev...

AI Technical Summary

Problems solved by technology

[0006] 1: Special personnel must be assigned to monitor during the maintenance process;

[0007] 2: Electrical inspection must be done before work;

[0010] However, as buildings become larger, many buildings are equipped with multiple power distribution rooms, and each power distribution room is equipped with a large number of switch cabinets. Power supply companies usually face the problems of insufficient operation and maintenance personnel and low maintenance efficiency.

And the maintenance personnel generally just simply check the monitoring instruments on the switchgear. If the monitoring instruments fail or are damaged, it is difficult for the maintenance personnel to judge the fault immediately. For some important switchgears, such as data centers, hospitals and other important places, they cannot immediately Power failure and breaker inspection and maintenance, if there is a short circuit in the switch cabinet at this time, it is very dangerous for people to approach, and it is often difficult for maintenance personnel to prevent this situation

[0011] According to the above discussion, it can be seen that the current inspection method of switchgear still exists at the same time with monitoring devices and manual inspection, and manual inspection wastes a lot of labor resources, and there is still a certain degree of danger in manual inspection. High, can monitor the parameters of the switchgear in real time, and at the same time realize the system of regular automatic inspection of the switchgear
