High voltage distribution cabinet HXGN15-12
The cabinet is usually assembled from aluminum-tohy steel sheets according to the modular principle, which have high mechanical strength and good corrosion resistance.
Description
marker
Scope
It is applicable to a three -phase system of distribution of alternating current of 10 kV (also applies to 12 kV), 50 Hz, and can be widely used in the construction and reconstruction of urban networks and agricultural networks, industrial and mining enterprises, high -rise buildings, public facilities, residential villages and other places, as a power supply unit of the ring network and the windows equipment, and plays a role in the distribution of electricity, management and protection of electrical equipment.
Structural characteristics
1. The structure of the cabinet
The cabinet is usually assembled from aluminum-tohy steel sheets according to the modular principle, which have high mechanical strength and good corrosion resistance. 2. The cabinet can be divided into independent compartments, such as the tire room, the switching room, the cable room and the dash room, which are isolated from each other to ensure the safety and reliability of the equipment. 4.
2. The sales switch
The load switch with sulfur hexaffeoride or a combined load switch with a fuse with an isolated case inside. The load on the basis of the sulfur hexftoride has such characteristics as small size, low weight, ease of operation, light working effort, reliable blocking, does not require maintenance, etc. 2.
3. The structure of the discharge of pressure
The back of the cabinet is usually equipped with a pressure discharge channel, which can drop the pressure in time to protect the safety of operators in case of malfunction inside the circuit of the circle2.
Advantages of performance
1. The good electrical characteristics: the nominal current is usually 630A and lower, which can satisfy the demand for the distribution of electricity and control in various scenarios. Due to the high strength of insulation and explosive ability, it can ensure stable operation of the energy system.
2. Function of the blocking: it is equipped with a perfect function of the “five -profile blocking”, i.e. Prevention of opening and closing the switch with a load, preventing the wrong entry into the charged interval, preventing improper opening and closing the main switch, preventing the closure of grounding equipment with electricity, preventing the ground switch from the supply of electricity when closing, which effectively prevents the safety risk caused by improper operation.
3. Bending and convenient operation: it can be manually controlled or electrically, which is convenient for users to choose in accordance with the actual needs.
