Product Description

Description

indoor permanent magnet solid-sealed high-voltage vacuum circuit breaker is an indoor switchgear of a three-phase AC 50Hz rated voltage of 12KV power system, used as power grid equipment, industrial and mining enterprises
Protection and control unit for industrial power equipment. It is suitable for places requiring frequent operation under rated working current, or multiple interruption of short-circuit current.
The circuit breaker adopts an integrated design of the operating mechanism and the circuit breaker body, which can be used as a fixed installation unit or equipped with a dedicated propulsion mechanism to form a handcart unit.
Outdoor Potential Transformer (PT)
Definition and function: Voltage transformer (PT) is mainly used to convert high voltage into low voltage (usually 100V) suitable for instrumentation or relay use, for measuring line voltage, power and electrical energy, or to protect valuable equipment in the line in the event of line failure.
Structure: PT consists of primary winding, secondary winding, iron core terminal and insulation support.
Working Principle: The working principle of PT is similar to that of ordinary transformer with no-load condition, which realizes voltage transformation by changing the ratio of winding turns.
Technical parameters: in the 110kV and above voltage level system, PT usually has two secondary windings, rated phase main secondary winding voltage is 100/31/2V.

Step-down transformer
Definition and function: Step-down transformers are used to reduce high voltage to a voltage level suitable for the safe use of the consumer, e.g. to reduce the voltage above 100,000V to 380V in a three-phase, four-wire system.
Technical parameters: The technical parameters of step-down transformer include rated capacity, rated voltage, no-load loss, no-load current, short-circuit loss and so on. For example, the no-load loss of S9-M-800/6 step-down transformer is 1400W, load loss is 7500W, no-load current is 0.8% and impedance voltage is 4%.

Use environmental conditions
This type of product is equipped with a bistable permanent surface mechanism. The mechanism is equipped with permanent magnets. The permanent magnets provide the holding force to maintain the switch in the closed and open state. Compared with the conventional spring operating mechanism, the number of mechanical parts is greatly reduced. The mechanical transmission chain is shortened, so that the reliability of the switch is greatly improved, and the mechanical life is greatly increased.
