General introduction

 

GW6A disconnect or is researched and developed by ourselves, which has reached the perfect standards of SGCC. Moving contact-head system of the disconnect or adopts scissors type structure, nice appearance, excellent electric and mechanical performance, good corrosion-prevention and anti-seismic function. Compared to other series disconnectors, GW6A disconnect or can effectively narrow longitudinal distance and save occupation area which further saves leading wires and pillar insulator, etc. it has the following characteristics: GW6A is single column, vertical contact break, double arms shrinkable type, disconnect or, consisting of 3 poles, which manipulated through electrical interlocking. Each pole mainly includes: pedestal, pillar insulator, rotary insulator, main blade, static contact-head, operated mechanism, etc. it can be equipped with earthing switch according to different requirements.

 

Product Features:

 

GW6A series is single column, 2 arms, vertically contact break, (scissors type) disconnect or, can be equipped with JW7 Type earthing switch. The disconnect or standard configuration adopts CJTKA type motor operated mechanism with 3 poles interlocking manipulation. Earthing switch adopts CS17A type manual operated mechanism with 3 poles interlocking manipulation. It can be equipped with CJTKB motor operated mechanism according to different requirements.

 

1), GW6A series disconnect or is single column, vertically contact break, double arms folding structure. Blade switching is clearly visible, convenient for patrol. Short distance between phases, small longitudinal space occupation when blade closing, quite convenient for busbar disconnect or. Clamps on moving contact-head have wide connection range and powerful ice-breaking ability.

 

2), conductive joint adopts flexible connection for transition. There are no moving connecting points on hinged parts of all fixed power conductive contact surface, which have been painted with sealant to prevent water and humid air infiltration. This treatment has greatly strengthened its power conductivity, power flow and corrosion-prevention ability.

 

3), main loop circuit adopts solid, high-quality and high-conductivity aluminum-alloy materials, anodic oxidation treatment on conductive tubes surface, which enables it high mechanical strength and corrosion-prevention.

 

4), transmission case for main blade adopts wholly-sealed structure. Transmission lever, balancing spring and clamping linkage are all placed inside of the case, which handled both birds nesting inside and transmission failure caused by outside environmental impact.

 

5), mechanical interlocking between main blade and earth blade is realized by cam plate structure installed on main blade and earth blade shaft in middle phase pedestal. Interlocking device can provide strong mechanical strength, direct manipulation and reliable interlocking.

 

6), main blade and earth blade transmission lever adopts assembly type. One side connection adopts U-shaped bolt connected with hoop, other side adopts adjustable connector of two start linkage, effectively avoid soldering and drilling in working site. This design is quite convenient for customers in working site installation, debugging, disassembly and maintenance.

 

7), rotating parts adopt stainless steel shaft, stainless steel joint bearing, Teflon bushing or self-lubricating composite shaft sleeve. All steel-made components are hot galvanized treatment.

 

8), earthing switch of 252 kV and below uses one-step manipulation, simple structure and light operating force. Earthing switch of 363 kV and above uses two-steps manipulation structure, strong short-circuit current withstanding ability, accurate statistic for switching inductance current.

 

9), motor operated mechanism case is made by stainless steel soldering. Manual operated mechanism is made of aluminum-alloy materials, nice appearance and good sealing. Reduction gear case of motor operated mechanism consists of famous-brand components and parts from joint ventures, good sealing and stable operation with noiselessness. The product uses national famous brand components, which has reliable working performance and complete function for locking.

Product introduction

 

GW4G Series perfection type disconnect or is 2 columns, horizontally rotary, single break type, HV, AC, disconnect or, including 3 single pole, of which are II Series 2 column frame structure, mainly constituted of pedestal, pillar porcelain and conductive parts. There are 2 pillar insulators vertical to the ground and parallel to each other on each pole, which respectively fixed on the bearing pedestal connected with the base, driven by a set of 4 linkages mechanism. Conductive blade consists of left and right contact-head, which separately fixed on pillar insulator.

 

This Series disconnect or adopts self-operated type contact-finger structure. Contact base and conductive levers are soldering connection to improve conductive reliability.

 

The disconnect or is designed to single pole type, which is driven by lever between pole and pole to realize 3-pole simultaneous linkage operation. Both main blade and earth blade can be equipped with CS17A manual operated mechanism. The main blade can also be equipped with CJTK motor operated mechanism. CS17A new-type manual operated mechanism can be equipped with DSW electromagnetic lock, of which hanging hole can be previously prepared.

 

Product Features

 

GW4G Series disconnect or is researched and developed by ourselves based on manufacturing of GW4 III Series, a new-style disconnect or which has reached the perfect requirements of SGCC, mainly focusing on design perfection in loop circuit heating, improvement in conductive reliability, prevention for driving parts failure, protection against rust and corrosion on bearing pedestal, corrosion-prevention on disconnect or appearance, simplified installation on construction site, debugging, etc. The specified features are followed.

 

Solution for Loop Circuit Heating

 

Main conductive loop circuit adopts rod-type, self-operated contact finger structure. The contact finger is made of special copper-alloy, which ensures good flexibility and high-temperature stability. Contact head system does not require the spring pressing contact point, it depends on itself elastic deformation to produce contact pressing force. So, the contact head and contact finger can maintain stable pressing force and do not change in long operation terms.

 

The contact head and contact finger adopt silver-plated graphite with dry lubricating plated technology, effectively handled dust condensation caused by painting conductive grease, which would further lead to enlargement phenomenon of contact electric resistance.
