Switching device and heat dissipation control method thereof

Abstract

The invention provides a switch device and a heat dissipation control method thereof.The switch device comprises a circuit breaker chamber, a bus chamber, an instrument chamber, a cable chamber and a heat dissipation module, an assembly chamber is arranged in the circuit breaker chamber, the heat dissipation module is detachably connected with the assembly chamber, a main air inlet of the heat dissipation module is communicated with the environment, and an auxiliary air inlet of the heat dissipation module is communicated with the bus chamber. A main air outlet of the heat dissipation module is communicated with the circuit breaker chamber; a pressure relief channel is formed between the bus chamber and the instrument chamber, an inlet end of the pressure relief channel is communicated with the circuit breaker chamber, an outlet end of the pressure relief channel is provided with a pressure relief device, a heat exchange channel is arranged in the cable chamber, the heat exchange channel is separated from an inner cavity of the cable chamber, and the heat exchange channel is communicated with the circuit breaker chamber; according to the invention, through the arrangement of the heat dissipation module, the pressure relief channel and the heat exchange channel in the switch device, ventilation and heat dissipation can be carried out on each chamber, so that heat dissipation can be carried out on each chamber in the switch device timely and effectively.

Description

technical field [0001] The invention relates to a switchgear and a heat dissipation control method thereof, in particular to a mid-mounted switch cabinet and a heat dissipation control method thereof. Background technique [0002] For switchgears such as mid-mounted switchgear, they are often used for control, protection, monitoring and measurement of power circuits, such as power plants, power transmission of small and medium generators, and secondary substations of power systems. Electricity, power transmission, distribution of industrial and mining enterprises and institutions, and starting of large high-voltage motors, etc. [0003] For the conventional mid-mounted switchgear structure, it is often divided into an upper, middle and lower three-layer structure. The upper layer is the busbar room and the instrument room (isolated from each other), the middle layer is the circuit breaker room, and the lower layer is the cable room. In the actual operation of the central sw...
