GW1 series 11kV 400A disconnector and air breaker switch

Short Description:

All overhead power transmission lines require an Air Break Switch, which is primarily used to connect or disconnect (on/off switching) the power system of a specific section of overhead line and transformer from the main distribution line. This enables the user to isolate a section of the overhead wire without disrupting the remaining power transmission system.

LSOLATING SWITCH

GW1 outdoor AC high-voltage disconnector is applicable to the device on the line of outdoor high-voltage distribution equipment, which is used to cut off the line and convert the line when there is voltage and no load.

This product is a three-phase electrical appliance composed of three separate single pole disconnectors. Each single pole disconnector has the same components, such as base, post insulator, front and rear static contacts, knife switch and arc angle, etc.

This series of disconnectors meet the requirements specified in gb1989-89 AC high voltage disconnectors, iec1129 (1984), AC disconnector grounding switches and iec694 (1980) common terms for high voltage switchgear and control equipment. This series of products have good seismic resistance and meet the requirements of 9 degrees of earthquake (horizontal acceleration 4.9m/s2 and vertical acceleration 2.45m/s2).

PRODUCT DETAILS

>> GW1 disconnector

GW1 switch is a double column outdoor high-voltage disconnector composed of three single poles. The switch is a one-way opening type. It is composed of base, insulator, knife guide and conductive part. Each pole has two post insulators fixed on both sides of the base, and there are pull rod insulator, crank arm and rotating shaft in the middle to open or close the switch. The switch can be equipped with anti-theft operating mechanism or ordinary operating mechanism.

function

Safety  protection   //  Corrosion resistance  //  Outdoor  rainproof  //  Long life  //  Excellent material

>> Structural features

The disconnector is composed of three identical single pole disconnectors. During installation, the three poles are integrated by the pipe connecting rod, and equipped with cs8-1 manual operating mechanism. Each single pole disconnector has a separate iron frame, two post insulators are installed at both ends, and contacts are installed on them. There is a rotating shaft in the middle of the iron frame, and the knife switch is opened and closed with the help of pull rod insulator.

>> Hidden danger

The use of inferior disconnector will lead to porcelain bottle fracture fault and overheating of conductive circuit. During operation, the spring will be compressed for a long time due to static contact finger compression.
If the working current is large and the temperature rise exceeds the allowable value, its elasticity will deteriorate and a vicious circle will eventually cause burning loss and endanger life safety!
