ZN63vs1 High Voltage Vacuum Switch Installation Manual-vs1 Vacuum Circuit Breaker Series Taikai Free Supply-Shaanxi Taikai High Voltage Switch Manufacturing Co., Ltd. Indoor switchgear with AC 50Hz rated voltage of 12kV power system is used as protection and control unit for power grid equipment, industrial and mining enterprise power equipment. It is suitable for places requiring frequent operation under rated working current, or breaking short-circuit current multiple times. The circuit breaker adopts the integrated design of the operating mechanism and the circuit breaker body. It can be used as a fixed installation unit or can be equipped with a special propulsion mechanism to form the role of a handcart unit. Second, the model and meaning
Outline drawing of ZN63A-12 indoor high voltage vacuum circuit breaker
Product structure and characteristics of ZN63A-12 indoor high-voltage vacuum circuit breaker V. Vacuum arc extinguishing chamber: The circuit breaker is equipped with a middle-sealed ceramic or glass vacuum arc extinguishing chamber, using copper-chromium contact materials, cup-shaped longitudinal magnetic field contact structure , The electrical wear rate of the contact is small, the electrical life is long, the pressure resistance level of the contact is high, the dielectric strength of the medium is stable, the recovery speed after the arc is fast, the level of the cut-off level is low, and the opening capacity is strong. Sixth, the overall structure of the overall structure of the circuit breaker adopts the operating mechanism and the arrangement of the arc extinguishing chamber, the main conductive circuit part is a three-phase floor structure, the vacuum arc extinguishing chamber is installed longitudinally in a tubular insulating cylinder Oxygen resin is cast by APG process, so it is particularly resistant to creepage. This structural design greatly reduces the accumulation of dust on the surface of the arc extinguishing chamber, which not only prevents the vacuum arc extinguishing chamber from being damaged by external factors, but also ensures that it can exhibit high resistance to voltage effects even in humid, hot and severely polluted environments state. Seven, the main circuit current path when the circuit breaker is in the closed position: 1, the upper outlet 28 passes through the upper bracket 27 fixed on the arc extinguishing chamber to the static contact inside the vacuum arc extinguishing chamber, and conducts electricity through the moving contact and its connection Clip, soft connection, to the lower bracket 30, the lower outlet 32. The insulating rod 34 and the internal disc spring 33 pass through the circuit breaker connecting rod system to complete the operation movement of the circuit breaker and keep the contacts in contact. 2. Each current level of the circuit breaker is equipped with a dust-proof insulating cylinder cover when it leaves the factory. In actual use, the rated current of 1250A and below must not be removed. The rated current of 1600A and above must be removed. Eight, operating mechanism 1, the operating mechanism is a flat spring storage type operating mechanism, with manual energy storage and electric energy storage function, the operating mechanism is placed in the mechanism box in front of the arc extinguishing chamber, the circuit breaker mechanism The box is also used as the framework of the operating mechanism. The mechanism box is divided into five assembly spaces by four intermediate partitions, during which the energy storage part, the transmission part, the trip part and the buffer part of the actuator are respectively installed, and the front part is provided with a closing and dividing button, a manual energy storage operation hole, Spring energy storage status indicator, closing indicator. In this way, the arc extinguishing chamber and the mechanism are arranged in front and back to form a whole, making the two more consistent, reducing unnecessary intermediate transmission links, reducing energy consumption and noise, and making the circuit breaker function more reliable. 2. The circuit breaker has the advantages of long service life, simple maintenance, no pollution, no explosion hazard, and low noise. It is more suitable for harsh operating conditions such as frequent operation. The circuit breaker can be installed in the handcart switchgear. Can also be used for fixed switchgear.
