The Main Function Of Vertical Fuse Disconnector

vertical fuse switch disconnector equipment is used in power systems with a rated voltage of 12 kV and AC 50 Hz and below. It is equipped with a CS6-1 type manual operating mechanism to open and close circuits when there is voltage but no load. It also has derivative products such as anti-pollution type, plateau type, and configuration functions such as adding a live display device and adding a sensor. What are the main functions of nhrt40 vertical fuse switch disconnector?

Performance characteristics of high-voltage disconnectors
The conductive part of the high-voltage disconnector is mainly composed of a contact knife and a static contact. The static contact is installed on the support insulators at both ends. Each phase contact knife is composed of two slot-shaped pictures. It not only increases the heat dissipation area of ​​the contact knife, which is beneficial to reducing the temperature rise, but also improves the mechanical strength of the contact knife, so that the dynamic stability of the switch is improved. One end of the contact knife is installed on the static contact through a shaft pin, and the other end of the contact knife is separably connected to the static contact system, and the contact pressure of the contact is maintained by the contact springs at both ends. Chassis assembly: It consists of the chassis main shaft and the limit plate. The limit plate is mainly used to ensure that the conductive contact knife reaches the required end position when it is "opened" or "closed".
The high-voltage isolating switch is used to isolate the high-voltage power supply to ensure the safety of maintenance of other electrical equipment (including lines). The high-voltage isolating switch does not have an arc extinguishing device, so it cannot cut off the load current and short-circuit current, but it can be used to switch on and off a certain small current. For example: the excitation current does not exceed 2A, the capacitive current of the no-load transformer does not exceed 5A, and the circuits such as voltage transformers and lightning arresters.
Indoor high-voltage isolating switches are suitable for high-voltage cabinets and ring network cabinets. They are widely used to ensure the safety of high-voltage electrical equipment during maintenance work and play a role in isolating voltage.
