Structural characteristics
Corps structure
1.Chosf has a fully assembled design, which is made of high-quality steel sheet with zinc-aluminum coating by multiple flexion and welding, with high mechanical strength and good anti-corrosion characteristics. The processing process of zinc-aluminum steel sheet is advanced, which allows maintaining stable work for a long time in severe environmental conditions.
2. The camshaft is divided into four independent compartments, namely: the tire compartment, the power circuit breakers, the cable compartment and the instrument compartment, and each compartment is isolated by metal partitions, which effectively prevents the spread of malfunctions and increases the safety and reliability of the equipment.
3. The cabinet is equipped with high -strength loops and a door blocking device, which is simply in operation and is well sealed, and can effectively prevent dust and moisture from getting into the cabinet.
The structure of the manual cart
1. The vegetable for the circuit breaker has a central structure, which can be easily pushed and extended. The guide carts are made of high -strength alloy steel with a special surface treatment, which has good wear resistance and direction that provides smoothness and accuracy of the trolley during movement.
2. The carts of the carts are installed vacuum switches, current transformers, grounding electrics and other main electrical components that are connected by insulated passage insulators and tires, which provides a reasonable layout and ease of maintenance and overhaul.
Operational advantages
Electric characteristics
1. The number voltage is 40.5 kV, and the rated current can be configured in accordance with the user requirements, usually 630A, 1250A, 1600A, 2000A, 2500A, 3150A and so on.
2. The use of a vacuum switch as a main switching element has the advantages of strong disconnecting capacity, good ardent capacity and a long service life. Contacts of the vacuum circuit breaker break the current in a vacuum, which avoids ablation and oxidation of contacts with an arc and increases the reliability and stability of the circuit breaker.
3. Injected with perfect devices of relay protection and measuring devices, it can carry out distance control and control of the distribution device, which increases the intellectual level of equipment.
Safety characteristics
1. The perfect function of blocking with five protection is made, i.e. prevention of erroneous opening and closing of the circuit breaker; prevention of opening and closing the disconnector with the load; prevention of electric freezing (closing) of grounding wires (grounding); Prevention of the circulation of the circuit breaker (disconnector) with the grounding wire (grounding ground); and preventing an erroneous entry into electrically charged gaps. The locking device with five protection uses a combination of mechanical and electrical locking to ensure the safety of operators.
2. The distribution device is equipped with a pressure discharge channel and a pressure discharge device inside a camshaft, which can timely discard the pressure in a timely malfunction inside the distribution device to prevent the abroad expansion.
