Abstract

The utility model relates to the lead supporting device of a transformer on-load voltage regulation switch and belongs to the technical field of transformers. According to the technical proposal of the utility model, the lead supporting device comprises a fixed plate (3), a supporting plate (2), an insulating cylinder (1), an insulating rope (4) and insulating paper boards (9). The fixed plate is welded at the case bottom of a transformer and is connected with the insulating cylinder. The supporting plate is bound with the insulating cylinder through the insulating rope. The upper surface of the supporting plate is provided with a plurality of insulating paper boards and the insulating paper boards are the same with the supporting plate in shape. The lead supporting device is provided for supporting a lead and reduces the load on a switch exerted by the gravity of the lead. Meanwhile, hidden troubles caused by the drawn damage of the switch are avoided. Since the main body of the supporting device is made of insulating material, the electrical performance of leads can be met.

Description

A kind of on-load tap-changer of transformer lead-in wire bracing or strutting arrangement
Technical field
The utility model relates to a kind of on-load tap-changer of transformer lead-in wire bracing or strutting arrangement, belongs to the transformer technology field.
Background technology
On-load tap-changing transformer is the tap position that changes transformer through on-load voltage regulating switch, makes transformer under situation about not opened circuit, carry out the transformer of pressure regulation.The scope of its pressure regulation has ± 8 grades, ± 10 grades, ± 16 grades etc.Its range of regulation is big more, and the lead-in wire that just has more voltage regulation coils is received on the tap changer, is connected to the gravity of a large amount of lead-in wires generations of switch, can produce very big tensile load to switch, even can damage switch.
The utility model content
The purpose of the utility model provides a kind of on-load tap-changer of transformer lead-in wire bracing or strutting arrangement, is used for supporting wire, the gravity that reduces to go between is to the load that switch causes, and has stopped the hidden danger that switch is drawn damage, solves the problems referred to above that background technology exists.
The technical scheme of the utility model is: a kind of on-load tap-changer of transformer lead-in wire bracing or strutting arrangement; Comprise fixed head, supporting bracket, insulating cylinder, insulation rope and insulating board; Fixed head is welded at the bottom of the transformer tank; And be connected with insulating cylinder, supporting bracket on insulating cylinder, is provided with a plurality of insulating boards identical with the supporting bracket shape through the colligation of insulation rope above the supporting bracket.
Insulating cylinder is provided with hand hole, conveniently is connected with fixed head.
Fixed head is fixedly connected with insulating cylinder through bolt, nut, packing ring; Insulating cylinder wall thickness and highly can customizing as required, supporting bracket is processed by the lamination insulating board, and supporting bracket and insulating cylinder have aperture; The insulation rope is through aperture colligation supporting bracket and insulating cylinder; A plurality of insulating board thickness are different, and quantity can increase and decrease, and are used for regulating height.
The good effect of the utility model: the utility model is used for supporting wire, has reduced lead-in wire gravity to the load that switch causes, and has stopped the hidden danger that switch is drawn damage, and supportive body adopts insulating material simultaneously, has also satisfied the electric property of lead-in wire.
