Analysis of configuration requirements for cold storage high and low voltage electrical equipment
First of all, Shanghai Cold Storage Installation Company reminds high-voltage power distribution equipment to have five preventive measures, cold storage construction, and: to prevent mis-closing, mis-distribution of switchgear; to prevent load separation and closing switch; to prevent live grounding; to prevent grounding Closing to prevent staff from entering the charging interval.
Wiring should be as simple as possible. Power transformers below 800kva should use load switches with fuse protection. For oil-immersed power protectors of 800kva and above, high-voltage circuit breakers should be used, and relay protection can be used with the device that can cut off the power supply and the gas protection of the transformer.
The main circuit circuit diagram, operating procedures and precautions should be attached to the inside of the high voltage distribution room door.
Insulated wires should be used for the busbars.
The high-voltage inlet and outlet lines should take into account the installation location of the cable and facilitate testing.
Requirements for low-voltage power distribution equipment: analysis of configuration requirements for cold storage high and low voltage electrical equipment
Wiring should be as simple as possible. Generally, there is no isolation switch installed in front of the circuit breaker. The number of low-voltage outlet circuits should not exceed 8 circuits.
The zero busbar (centerline) interface should not be less than 1/2 of the main busbar section; when the phase section is below 50mm2, the centerline takes the same section as the phaseline. Analysis of configuration requirements for cold storage high and low voltage electrical equipment
The main circuit circuit diagram, control circuit diagram, operation procedure and precautions are attached to the inside of the low-voltage power distribution room door. According to the need of reactive power compensation, the power capacitor can be configured. The Shanghai refrigerator supplier reminds that its capacity is generally 15% of the transformer capacity. ~20%. If you want to know the cold storage price you need, Shanghai Xueyi Refrigeration is a refrigeration engineering company engaged in cold storage installation, cold storage design, cold storage after-sales maintenance and repair. The cold storage construction team has many years of on-site construction experience. Install cold storage, cold storage price, welcome you:
