Intelligent medium voltage switch cabinet

Abstract

The invention relates to the technical field of electrical power system equipment, in particular to an intelligent medium voltage switch cabinet. The intelligent medium voltage switch cabinet comprises a closed metal cabinet body. A handcart chamber, a bus chamber, a cable chamber and a meter chamber are arranged in the cabinet body in a separated mode. An intelligent disconnector is arranged in the handcart chamber. The intelligent disconnector comprises a control box, a three-phase moving contact and an electric chassis truck. A mechanical property on-line monitoring device, a disconnector control loop parameter measurement device and an intelligent control module are arranged in the control box. A communication interface connected with the intelligent control module is arranged on the upper portion of the control box. An intelligent module data acquisition device connected with the communication interface is arranged in the meter chamber. The intelligent medium voltage switch cabinet has the functions of intelligent monitoring, intelligent diagnosis and intelligent control, and is compact in structure, good in mechanical performance and electrical performance, and safe and reliable in operation.

Description

technical field [0001] The invention relates to the technical field of power system equipment, in particular to an intelligent medium-voltage switchgear. Background technique [0002] The stable operation of the power system not only affects the sustainable development of the national economy, but also is closely related to the daily life of the people. With the development of science and technology, the production of various industries and the life of residents put forward higher and higher requirements for the quality and management of power supply. The State Grid Corporation also proposed the concept of smart grid. As the basic unit of the power grid, 10KV medium voltage switchgear must change the traditional design and control mode in order to conform to the trend of social development and lay the foundation for the realization of smart grid. [0003] The traditional medium-voltage switchgear uses a closed metal cabinet, so it is impossible to know the operating status ...

AI Technical Summary

Problems solved by technology

[0003] The traditional medium-voltage switchgear adopts a closed metal cabinet, so it is impossible to know the operating status of the switchgear in the cabinet in time

After the switchgear breaks down and then repair and replace it, the maintenance personnel cannot quickly and accurately detect the fault condition and the fault location in the switch cabinet, and the occurrence of this fault is sudden, without any early warning, and it is possible Cause explosions, fires and other accidents that seriously endanger personal safety, and at the same time affect the reliability of the power supply and distribution network, which will cause major economic losses and cause serious social impact

The traditional medium-voltage switchgear has a low degree of intelligence, due to unreasonable structural settings, large volume, unstable mechanical transmission mechanism, and low technical indicators
