Abstract
The utility model relates to a tapping switch insulating structure for a transformer, and belongs to the technical field of mounting of transformer equipment. According to the technical scheme, the tapping switch insulating structure comprises a transformer oil tank cover (1), an insulating base plate (2), upper core clamping pieces (3) and a tapping switch (4), wherein the tapping switch (4) is arranged in the transformer; one end of the tapping switch (4) penetrates through the transformer oil tank cover (1), and is fixedly arranged on the transformer oil tank cover (1), and the other end of the tapping switch (4) is connected with a primary winding of the transformer; the insulating base plate (2) is arranged between the tapping switch (4) and the transformer oil tank cover (1), and is fixedly arranged on fixing plates of the upper core clamping pieces (3) on the two sides of the tapping switch (4). The tapping switch insulating structure has the beneficial effects that the tapping switch is prevented from contacting with a transformer oil tank and the upper core clamping pieces after being lifted in an assembly process of the transformer, so that the multipoint grounding of the transformer is completely eradicated, and convenience is provided for the mounting and the use of the transformer.
Description
Technical field
The utility model relates to a kind of sub-connecting switch of transformer insulation system, belongs to transformer equipment mounting technique field.
Background technology
In transformer, owing to regulating the needs of former secondary voltage ratio, in transformer, be all provided with shunting voltage regulating switch, shunting voltage regulating switch adopts suspended structure more, switch is fixed on case lid, be integrated with oil tank joint, then ground connection, and in the assembling process of transformer, because case lid can not be buckled in it device, so now, switch need be supported on assembling and the semi-finished product test of on upper clamping piece fixed head unshakable in one's determination, carrying out tap line temporarily, after the device body of transformer and lead-in wire assembling and semi-finished product have been tested, device body just can be in place at fuel tank internal, then button cover, finally, need on case lid, will on switch, carry, and be fixed on case lid, make itself and oil tank body have reliable contact, and final one point earth.In order to prevent the generation of the inner circulation of transformer, fuel tank and core clamping need mutually insulated, and ground connection respectively, and due to the design feature of suspension type switch, on switch, the amount of carrying is less, switch is often generation and the situation that fuel tank, core clamping all contact after upper carrying, and has caused the multipoint earthing of transformer, to transformer install and use and on-the-spot issue handling has caused very large difficulty.
Utility model content
The utility model object is to provide a kind of sub-connecting switch of transformer insulation system, in the assembling process of transformer, prevents the multipoint earthing of transformer, guarantees installing and using of transformer, solves the problem existing in background technology.
The technical solution of the utility model is:
A kind of sub-connecting switch of transformer insulation system, comprise transformer oil tank cover, insulating pad, upper clamping piece unshakable in one's determination and shunting switch, shunting switch is located in transformer, one end is passed from transformer oil tank cover, and be fixed on transformer oil tank cover, winding of other end connection transformer, is provided with insulating pad between shunting switch and transformer oil tank cover, and insulating pad is fixed on the upper clamping piece fixed head unshakable in one's determination of shunting switch both sides.
Described insulating pad size matches with shunting switch.
The beneficial effects of the utility model are: in the assembling process of transformer, avoid shunting switch to contact with oil tank of transformer, upper clamping piece unshakable in one's determination after upper carrying, stopped the multipoint earthing of transformer, provide convenience to installing and using of transformer.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: transformer oil tank cover 1, insulating pad 2, upper clamping piece unshakable in one's determination 3, shunting switch 4.
Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
With reference to accompanying drawing 1, a kind of sub-connecting switch of transformer insulation system, comprise transformer oil tank cover 1, insulating pad 2, upper clamping piece 3 unshakable in one's determination and shunting switch 4, shunting switch 4 is shunting voltage regulating switch, adopt suspended structure, be arranged in transformer, one end is passed from transformer oil tank cover 1, and be fixed on transformer oil tank cover 1, winding of other end connection transformer, between shunting switch 4 and transformer oil tank cover 1, be provided with insulating pad 2, insulating pad 2 sizes match with shunting switch 4, insulating pad 2 is fixed on upper clamping piece unshakable in one's determination 3 fixed heads of shunting switch 4 both sides.
Claims (2)
1. a sub-connecting switch of transformer insulation system, it is characterized in that comprising transformer oil tank cover (1), insulating pad (2), upper clamping piece unshakable in one's determination (3) and shunting switch (4), shunting switch (4) is located in transformer, one end from transformer oil tank cover (1) through, and be fixed on transformer oil tank cover (1), winding of other end connection transformer, between shunting switch (4) and transformer oil tank cover (1), be provided with insulating pad (2), insulating pad (2) is fixed on upper clamping piece unshakable in one's determination (3) fixed head of shunting switch (4) both sides.
2. sub-connecting switch of transformer insulation system according to claim 1, is characterized in that described insulating pad (2) size matches with shunting switch (4).
