The RMU rated current is not large, so RMU high voltage switches are typically taken by high voltage switches with a simple structure without using high-voltage fuse of the complex structure of the circuit breaker. That is, the ring of high-voltage switch cabinet generally load switch. RMU operating with normal load switch current, short-circuit current with fuse removal, Hefei XL-21 market price, both of which combine to replace the circuit breaker. Of course, this can only be limited to a certain capacity. Such a switch cabinet power distribution system also can be used non-ring structure, XL-21, then with the wide application of this switchgear, "RMU" jumped out of the scope of the distribution ring and the pan It refers to the load switch high voltage switchgear the main switch. Outdoor ring network cabinet; editing conditions 1, ambient temperature: up to + 55 ℃ lower limit of -30 ℃; 2, no more than 3000 meters above sea level; 3, the earthquake intensity does not exceed 8 degrees; 4, relative humidity: daily average of not more than 95 %, on average less than 90%; 5, no fire and explosion hazards, no serious contamination, chemical corrosion and severe vibration. Means edits outdoor RMU computer is fully protected device for measurement, control, protection, communications integration, an economical protection; tailored to high-voltage power distribution cabinet distribution network terminal, with three-stage non-directional current protection core, monitoring and collection functions with network parameters, Jieshou XL-21, can dispense with the traditional ammeter, voltmeter, power meter, frequency meter, power meter, etc., Hefei XL-21 wholesale price, and through communication port The measurement data and the protection of information remote PC, easy to implement distribution automation; power supply apparatus according to the characteristics of the distribution network integrated standby power source to function in the device, the flexibility to achieve incoming line standby and bus-bus transfer function. XL-21 Market Hefei, Anhui Yu-liang Electric (certified), XL-21 provided by the Anhui Electric Co., Ltd. Yu Liang. Yu Liang Anhui Electric Co., Ltd. (www.ahyldq.com) is Hefei, low-voltage switchgear leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
