Overview:

(H) GW5 outdoor high-voltage isolating switch is used for three-phase AC 50Hz outdoor high-voltage electrical equipment, for the line to be separated under voltage and no load, as well as for the repair of high-voltage busbars, circuit breakers and other electrical equipment and charging The high voltage line is used for electrical isolation and can also be used to open small capacitors or inductor currents. An insulation distance that meets safety requirements is provided when the knife is in the normal opening position. Widely used in 35-110kV substation.

Main structure and characteristics:

1. Each isolation switch monopole consists of a base, two post insulators, a terminal block, left and right contact assemblies, and a grounding knife;
2. The shaft socket is used between the finger and the finger socket, and the copper soft connection is used between the terminal board and the contact rod, so that the main circuit resistance of the product is greatly reduced.
3. The two pillar insulators are installed on the same base in a "V" shape, which has the advantages of small footprint and reduced installation of metal frame;
4. It adopts rolling shaft transmission, which is easy to operate, flexible to rotate, and easy to open and close.
5. Rotate through the bevel gear to ensure that the opening and closing actions of the two columns are consistent;
6. The two pillars have an angle of intersection of 50 degrees and a rotation angle of 90 degrees. After the opening, there is a sufficient amount of insulation isolation fracture to ensure the safety;
7. The operating mechanism drives the base arm and the pull rod to rotate the two post insulators synchronously to realize the opening and closing operation.
8. The product has three modes: ungrounded, single grounded, and double grounded. There is a reliable mechanical interlock between the spindle and the ground to ensure its safety.
9. Equipped with CJ2 automatic operating mechanism or CS-17G manual mechanism, etc., can be equipped with electromagnetic lock. The positioning device on the operating mechanism can ensure that the contact and the static contact are in the correct contact position or the breaking position.
