Embodiment approach

[0045] A method for implementing a low-voltage switchgear with active cooling components, comprising the steps of:

[0046] Step 1: Lead the incoming cable 505 into the wire inlet 502, pass through the current detection sensor 503 and the protective wire sleeve 504 to extend the inside of the switchgear main body 1, and connect with the vacuum switch 1033, and the incoming wire can be adjusted through the wire inlet 502 The angular position of the cable 505 reduces the wear and tear of the incoming cable 505 and improves the service life;

[0047] Step 2: Connect the low-voltage circuit equipment through the drawer-type vacuum circuit breaker 103 and the cable busbar installation box 104, adjust the vacuum switch 1033 and the switch button 1013 to control the power switch, and adjust the drawer-type vacuum circuit breaker by telescopic electric cylinder 202 during maintenance and overhaul The position of 103 is convenient for operation, and can maintain the sealing effect of t...

Abstract

The invention discloses low-voltage switch equipment with an active cooling assembly and an implementation method of the low-voltage switch equipment, and belongs to the technical field of low-voltage switches. In order to solve the problems that the internal heat of the low-voltage switchgear cannot be timely discharged, the functionality is poor, the operation is inconvenient, and the cooling and heat dissipation effects are poor, during the long-term work of a switch cabinet, an external temperature and humidity sensor and an internal temperature and humidity sensor outside a side cooling box respectively detect the internal and external temperature and humidity of a switchgear main body; numerical values are displayed on a temperature and humidity display screen, a PLC opens different active cooling assemblies and a refrigeration compressor according to the temperature and humidity numerical values, cold air is released by compressing a coolant and a condenser, airflow is controlled through an air pressure valve, the cold air is guided into a side cooling box, and the cold air is guided into a switch equipment main body through a first induced draft fan; and hot air in the switch equipment main body is exhausted through an air exchange fan in the central cooling chamber, so that the heat dissipation efficiency is improved through multiple different heat dissipation modes, and the working effect is improved.

Description

technical field [0001] The invention relates to the technical field of low-voltage switches, in particular to a low-voltage switchgear with active cooling components and an implementation method thereof. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instruments, automatic controls, motor magnetic switches, various AC contactors, etc., some also have high-voltage room and low-voltage room switch cabinets, high-voltage busbars, such as power plants, etc. load shedding. The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, disconne...
