High and low voltage switchgear is a complete set of electrical equipment in the power system that connects high or low voltage cables. It mainly undertakes the functions of energy distribution, control, and circuit protection, and is widely used in substations, distribution systems, and new energy power stations. It achieves voltage conversion through transformers and integrates high-voltage and low-voltage chamber structures through components such as main control switches, circuit breakers, and contactors.
High and low voltage switchgear usually adopts modular design, including pull-out, distribution, armored and other types. Some models are equipped with ventilation and heat dissipation, dust-proof quick release, and temperature control systems to improve environmental adaptability. The new patented technology also introduces a movable roller mechanism and a spring buckle type heat dissipation network to enhance practicality. During installation, it is necessary to ensure the stability of the base by positioning components and elastic pressure structures, and to cooperate with the power on test bench for AC/DC parameter detection to ensure safe operation.
