Description

A low-voltage electrical equipment control cabinet

technical field

The invention relates to the technical field of control cabinets, in particular to a low-voltage electrical equipment control cabinet.

Background technique

The control cabinet is to assemble the switchgear, measuring instrument, protective device and auxiliary equipment in the closed or semiclosed metal cabinet or on the screen width according to the requirements of electrical wiring. and the safety of surrounding equipment. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. Cut off the circuit or alarm with the help of protective electrical appliances in case of failure or abnormal operation. Various parameters in operation can be displayed by means of measuring instruments, and some electrical parameters can also be adjusted to prompt or send out signals for deviations from normal working conditions. Commonly used in various power generation, distribution and substations.

When the control cabinet is in use, because there are a large number of electrical components installed inside the control cabinet, after a long period of use, the inside of the electrical cabinet will accumulate a lot of heat. If the heat is not discharged in time, it is easy to cause damage to the electrical components due to high temperature. The existing control cabinet is equipped with a cooling fan, which discharges the hot air inside the control cabinet. In order to ensure the balance of air pressure, an air inlet will be set on the control cabinet, and a filter screen will be installed on the air inlet to cool the outside air. However, after long-term use, a large amount of dust will adhere to the filter, which will block the filter holes of the filter, making it difficult to discharge the heat inside the control cabinet, affecting the normal use of the control cabinet, and the use effect is not good. it is good.
