Structure and working principal of circuit breaker
ZW32-40.5 F type intelligent circuit breaker is mainly composed of integrated solid sealing pole column, current transformer, motor operating mechanism and box. This type of circuit breaker is designed for miniaturization. At the same time, it is equipped with manual opening and closing devices. The current transformer can be selected according to user needs.
The control of ZW32-40.5 F type intelligent vacuum circuit breaker is completed by the supporting intelligent control unit. The opening and closing operation can be realized locally, or it can be operated remotely from a distance through the communication interface. Other information about the circuit breaker can also be transmitted to the control center, and the communication channels can be selected from cable, optical fiber, GPRS/CDMA, GSM, etc.
The intelligent control unit is installed close to the circuit breaker and is connected to the circuit breaker through a control cable. The power supply of the intelligent control unit is divided into the main power supply, the main power supply is AC or DC 220V, which is obtained by the high-voltage line through PT: the backup power supply is provided by the battery (installed in the intelligent control unit box).When working normally, the main power supply charges the backup power supply: when the main power supply is lost, the backup power supply can still complete the control of the circuit breaker and other operations in the control unit. The backup power supply (at full load) can maintain the whole machine for not less than 48 hours of work.
The circuit breaker operating mechanism is equipped with a manual emergency opening handle, which is used for emergency opening operation in the event of a control system or power failure.
ZW32-40.5
Outdoor High voltage AC Vacuum circuit breaker
Working principle and process of circuit breaker
1. Arc extinguishing principle: ZW32-40.5 F type vacuum intelligent circuit breaker adopts a vacuum arc extinguishing chamber, which uses vacuum as the arc extinguishing and insulating medium, and has a very high degree of vacuum. When the moving and fixed contacts are electrically charged under the action of the operating mechanism, a vacuum arc will be generated between the contacts. At the same time, due to the special structure of the contacts, an appropriate longitudinal magnetic field will also be generated in the gap between the contacts, causing the vacuum arc to remain diffuse and the arc to be evenly distributed on the contact surface to burn and maintain a low isolation voltage. When the current naturally crosses zero, the remaining ions, electrons and metal vapor can be combined or condensed on the contact surface and the shield within the order of microseconds, and the dielectric insulation strength of the arc extinguishing chamber fracture is quickly restored, so that the arc is extinguished to achieve the purpose of breaking. Due to the use of longitudinal magnetic field to control the vacuum arc, the vacuum circuit breaker has a strong and stable ability to turn off the current.
2. Energy storage: ZW32-40.5 F type can store energy manually through the energy storage handle, or it can store energy motorized.
3. Closing operation: press the closing button on the intelligent controller locally, or remote control the closing operation from a distance, or use the opening and closing handle to close manually.
4. Opening operation: press the opening button on the intelligent controller locally, or remotely control the opening operation from a distance, or use the opening and closing handle to opening manually.

ZW7-40.5
Description
ZW7-40.5 outdoor high-voltage AC vacuum circuit breaker has the advantages of safe and reliable performance, easy maintenance, and long maintenance cycle. Due to the use of a new type of insulating material, the outer side of the arc extinguisher and the inner wall of the porcelain sleeve are noncondensing. The overall structure of the transformer placed in the mechanism box facilitates installation. It also avoids the oil, gas leakage and toxicity problems of other switches. Since the moving and fixed contacts of the circuit breaker are sealed in a vacuum arc extinguishing chamber, and vacuum is used as the insulating medium and arc extinguishing medium, it has a series of advantages unmatched by other types of switches. Therefore, this product is an ideal product to replace the DW multi-oil circuit breaker. The structure type of the operating mechanism box of this product in the middle of the circuit breaker is a central-mounted high-voltage vacuum circuit breaker. The shape, length and size of this type of circuit breaker are 260mm smaller than the original circuit breaker, which is suitable for installation in places with smaller spatial locations.
