Description
Technical field
The utility model belongs to field of power transformer manufacture more particularly to a kind of Combined air formula loaded switch and silicon
The connection structure of steel dry-type transformer.
Background technique
Combined air load ratio bridging switch is cylinder mailbox type, and small in size, price is low, can be realized voltage ripple of power network
When, can automatic or electronic movement to ensure the stabilization of voltage.Compared with vacuum on-load operation switch, there is structure to simplify, arc extinguishing
Reliably, reliable in action, long service life, low-cost advantage.General producer is switching and is being in transformer connection type at present
Guarantee electrical safety distance, what is generallyd use is the connection that Combined air load ratio bridging switch is placed in transformer side,
But not only patching operations are cumbersome for this mode, while also adding cable length, increase cost.
Utility model content
Goal of the invention: in view of the deficiencies of the prior art, the utility model lies in that a kind of new Combined air formula has load to open
The connection structure with dry-type transformer is closed, is able to solve the problem of wiring inconvenience, and save cable dosage, save the cost.
Technical solution: for achieving the above object, the utility model adopts the following technical solution:
The Combined air formula is had load by a kind of connection structure of Combined air formula loaded switch and dry-type transformer
Switch, which is fixed on transformer body front face B-phase by switch pedestal, to be set, the switch pedestal and transformer body pedestal
It is connected；Insulating barrier is equipped between the Combined air formula loaded switch and transformer body, the insulating barrier is fixed
In the switch pedestal, several through-holes, Combined air formula loaded switch and transformer sheet are offered on the insulating barrier
Connecting line between body is connected across through-hole.
Preferably, the switch pedestal is welded by channel steel and steel plate.
Preferably, the switch pedestal includes a padded plate and two vertical bars, the Combined air formula
Loaded switch is placed on the padded plate, and the insulating barrier two sides are fixed in two vertical bars.
Preferably, the insulating barrier is epoxy plate of the thickness in 6-8mm.
Preferably, 3 row, 6 column through-hole is offered on the insulating barrier, connects and fix Combined air for wearing
Connecting line between formula loaded switch and transformer body.
The utility model has the advantages that compared with prior art, switch is placed in transformer front face B-phase and set by the utility model, and
It is isolated by insulating barrier, so that cable link install convenient, and safe distance is fixed reliable, while cable dosage is reduced,
Save the cost.

Specific embodiment
In the following with reference to the drawings and specific embodiments, the utility model is described further.
As shown in Figs. 1-2, a kind of Combined air formula loaded switch and dry type transformation disclosed in the utility model embodiment
Combined air formula loaded switch 2 is fixed on 1 front of transformer body by switch pedestal 3 by the connection structure of device, the structure
Face B-phase is set, and is isolated with transformer body 1 by insulating barrier 4, corresponding through-hole, switch 2 are offered on insulating barrier 4
Connecting line connect by the way that corresponding through-hole is incoming with transformer body 1, both ensure that safe distance, decrease cable and use
Amount.
Switch pedestal 3 with channel steel and steel plate as shown in figure 3, can be welded, and wherein pedestal and switch fix bore size
It is determined according to the fixation hole for switching bottom itself.Switch pedestal 3 is bolted with 1 pedestal of transformer body.To solid
Determine the position of the switch, is placed in transformer front center.Switch pedestal is equipped with a padded plate 31 and two vertical bars 32, compound to open
Pass is placed on padded plate 21, can highly be adjusted according to actual size, and insulating barrier is fixed in two vertical bars 32.
For insulating barrier 4 as shown in figure 4, can be made by epoxy plate, thickness can be 6-8mm, remove 3 rows 6 of pinout connector
Column outside totally 18 through-holes 41, also open 8 apertures 42 in two sides to fix with switch pedestal.Switch tap and transformer body point
The connecting line of connector uses cable connection, and through-hole is corresponded across insulating barrier both plays fixation on cable and insulating barrier
The effect of cable in turn ensures safe electrical distance.
