GW4 the open air isolates the switch train

GW4 series the open air it exchanges high voltage isolating switches to be outdoor high-pressure electric apparatus, 50Hz of three-phase alternating current, in the electric system used for nominal voltage 40.5-252kV, support the no-load change-over switching of high voltage line, and use the electrical apparatus and electrical isolation of the electrification high voltage line of high voltage bus, circuit breaker,etc. that are overhauled.

This series of products have the following varieties:

1. Press and earth the knife switch to divide: Earth non-groundedly and only, earth.

2. According to using the area to divide: General type, anti-pollution type, plateau type.

This series of products accord with every canonial requirement of national standard and IEC. The ability to resist earthquake of this series of products is good, can meet the requirement of 9 degrees in earthquake intensity.

Structure, operating principle

Series GW4 exchange the high voltage isolating switch including three are single-phase, every looks is the distyle structure, mainly made up of base, pillar electrical insulator, conductive part. Every phase have two insulating pillar, mount base at the the intersection of both ends and pedestal separately, in order to cross connecting rods are connected, the all right level is rotated. A point of two halves of conductive switch blade, fix on pillar electrical insulator separately, the contact point of the stylus is in the middle of two knob insulators.

When acting in operating mechanism, drive a column of the pillar electrical insulator to rotate 90& deg; ,Another insulating pillar transmits and rotates 90& deg at the same time because of the connecting rod; ,Then the switch blade turns towards with direction disintegration of one side. In order that operating sequence is correct while guaranteeing disconnecting switch and earthing switch, the goods in process or organization is equipped with the mechanical interlock, can guarantee to mainly divide the order movements mainly shut shutting dividing. Dividing of the earthing switch into type and Type¢ò.

The disconnecting switch makes single-phase pattern, can realize three phases are operated through the alternate connecting rod.
