The secondary communication distribution power supply panel is a product designed and manufactured by our company in accordance with the relevant regulations of the Ministry of Energy's "Norms for the Configuration of Power Plant and Substation Engineering and Relay Protection Test Instruments" and the Ministry of Electric Power Industry's "Key Points for Anti accident Measures of Power System Relay Protection and Automatic Devices". It provides a reliable, stable, and convenient AC power supply for the operation of on-site secondary equipment, meeting the requirements of the working power supply for on-site secondary equipment.

This equipment is suitable for power plants, substations, and large and medium-sized industrial enterprises, and can be used as a universal AC distribution power supply panel for secondary equipment.

1. Equipped with dual power supply, it can switch between manual and automatic modes. The use of contactors allows for load switching, improving the reliability of power supply.

2. The control of AC power supply adopts high breaking miniature circuit breakers, which have the advantages of fast action, high sensitivity, reliable action, and automatic tripping function for short circuit and overload.

3. There are many feeder lines.

4. It has the function of short circuit and overload trip alarm indication

1. Insulation resistance: Under standard test atmospheric conditions, the insulation resistance between each circuit of the device and the casing shall not be less than 10M Ω; the insulation resistance between each independent circuit shall not be less than 10M Ω.

2. Dielectric strength: Under standard test atmospheric conditions, the above-mentioned circuits and independent circuits can withstand AC 50Hz, voltage 2kV (effective value), and test for 1 minute without insulation breakdown or flashover phenomenon.

3. Impulse voltage: Under standard test atmospheric conditions, each AC circuit and DC circuit should be able to withstand a 5kV (peak) standard lightning wave short-time impulse test on the casing.

4. The communication circuit uses DZ47-60 small automatic switch, with a mechanical life of more than 20000 on-off cycles and an instantaneous breaking current of up to (4-7) Ie.
