Safety issues to be noted when installing vacuum circuit breakers
Before installation should be vacuum circuit breaker should be the appearance and internal inspection, vacuum interrupter, the parts, components should be complete, qualified, no damage, no foreign matter.
Installation of vacuum circuit breaker, should pay attention to the following issues:
1. Electrical safety is critical, we must ensure that the power supply has been cut off and the equipment has been grounded, while the wiring should be in line with the specifications to avoid short-circuit or overload, resulting in damage to the equipment.
2. Avoid severe vibration: In the installation process, to avoid severe vibration of the equipment. Violent vibration may cause the internal components of the equipment to loosen or damage, affecting the normal operation of the equipment.
3. In the installation process, tighten the fasteners with a dull wrench or plum or socket wrench, especially in the vicinity of the arc extinguishing chamber screws, prohibit the use of a live wrench.
4. Check the distance between the poles and position: check the distance between the poles and the location of the upper and lower out of the line distance must be in line with the relevant professional and technical regulations.
5. Use clean work tools: The work tools used must be clean and meet the requirements of assembly.
6. Apply lubricating grease: After the installation is completed, the distance between poles and the distance between the positions of the wires shall meet the requirements of the drawings and dimensions, and the rotating and sliding parts shall move freely, and the friction of the movement shall be coated with lubricating grease.
7. The installation sequence shall comply with the process regulations, and the fastener specifications of each component
shall be according to the design regulations.
8. Marking adjustable connection parts: After the overall installation and commissioning, it should be cleaned and wiped, and the adjustable connection parts of each component should be marked with red paint, and anticorrosive grease should be applied to the wiring at the outlet end.
12kV Vacuum Interrupter for Vacuum Circuit Breaker produced by Shaanxi West Power Tongzhong Electrical Co., Ltd. is the core component of the high-voltage power switch in the 12kV system, which is mainly used in the transmission and distribution control system of electric power. It has many excellent properties:
1. Good electrical conductivity: it can conduct current stably and avoid problems such as heating and energy loss due to excessive resistance.
2. Ultra-high contact reliability: close and reliable contact with the moving contacts, which is not easy to cause poor contact and loosening in the process of long-term use to ensure the normal operation of the circuit.
3. Strong abrasion resistance: due to friction with the movable contact in the process of opening and closing operations, it needs to have a certain degree of abrasion resistance to ensure that the contact performance and service life after long-term use.
