Oil-Immersed Type Load Break Switch for Oil-Immersed Transformer

Application:

This switch is used for compounded type transformer. It is classified into four-position and two-position

products. The four-position switch is divided into “T” type, “V” type and “I”. The switch is installed on the tank

well of compounded transformer, the transformer oil is used for its insulating and are eliminated material. It is

suitable for three phase power supply circuit with rated trequency 50Hz, rated voltage 10kV, 35kV, rated current

315 A and 630A. In the radial feed or loop feed supply system, it is used as controlling and protective device in

the industry civil used electric energy. When functioned by operating pole, the switch can drive three phase

linkage cut and close power resource or transfer supply method.

The on-load switch our company manufactures has innovative structure, excellent performance and high

reliability. It is tested qualified in every technical index b the National Transformer Quality Supervision and

Inspection Center. Its main features are as follow:

Feature:

1.The fixed contact of the same kind product is crab-claw form. With the increasing rotation of the switch, the

movable contact wears out more heavily, the pressure fixed contact put onto the movable contact declines, and

the contact resistance increases.

We change the fixed contact into clip-chip, and connect it with soft-connecting films, ensuring the contact

pressure with cylindrical spring to maintain a high contact pressure after 2000 times shifting and enable a

minimum contact resistance of fixed and movable contact. We also use high-quality copper alloy as the contact

material to make a lightest damage the arc will do to the contact when the contact shifts on-load, and enlarge

the contacting area to improve the current-passing capability.

2. Key components of our switch apply the overall steel casting technology, so the products are with high

mechanical strength.

3. Each plate-form spring has a deformation test before assembly to ensure the quality of the spring.

4. We use the latest type of insulation materials to ensure the switch a higher capability of withstand voltage

and withstand voltage.
