an electrical cabinet

Abstract

The invention discloses an energy-saving cabinet, and the cabinet comprises a replaceable drawer control loop, an energy-saving bypass control loop, a circuit breaker control loop, an in-cabinet illumination loop, and a measurement loop. The cabinet is advantageous in that if there is a fault and the loop needs to be switched to the other loop for use, the cabinet can achieve the direct switching from a bypass loop to the energy-saving loop or from the energy-saving loop to the bypass loop under the no cut-off condition when a user uses the energy-saving loop or the bypass loop is in operation, wherein the switching can be completed in 0.02S within a sine wave period, so the electric equipment does not need to be cut off.

Description

technical field [0001] The invention relates to an electric cabinet, in particular to an energy-saving cabinet. Background technique [0002] In the past, the large-capacity switching systems on the market were unable to achieve on-load switching. The so-called on-load switching means that the live equipment directly switches from one path to another for power supply under the condition of non-stop load. For example, if a low-voltage power distribution line needs to switch to another power supply, the back-end electrical equipment must be shut down and then switched. In the process of use, the production line process is very complicated. Some production processes stop production once and then restart, which will cost A lot of human, financial and material resources are required, and the operation is complicated, so professionals must be able to operate. Usually control the internal design of the electric cabinet. When the main components are broken, they can only be shut do...

[0002] In the past, the large-capacity switching systems on the market were unable to achieve on-load switching. The so-called on-load switching means that the live equipment directly switches from one path to another for power supply under the condition of non-stop load.

For example, if a low-voltage power distribution line needs to switch to another power supply, the back-end electrical equipment must be shut down and then switched. In the process of use, the production line process is very complicated. Some production processes stop production once and then restart, which will cost A lot of manpower, financial and material resources, and the operation is complicated, must have professionals to be able to operate

Usually control the internal design of the electric cabinet. When the main components are broken, they can only stop production and replace them for maintenance, which seriously affects the production efficiency and has certain dangers.
