Description

It is a kind of to prevent the structure deformed of sinking at loaded switch case lid

Technical field

The utility model is related to a kind of structures that prevents from sinking at loaded switch case lid and deform, and belong to power equipment technology neck Domain.

Background technology

At present, have for large size and carry for oil-immersed power transformer, because loaded switch own wt is big, by case lid top Portion supports, and case lid easily sinks to deforming herein.

The method of traditional deformation that prevents from sinking at loaded switch case lid is to weld many places on case lid to strengthen iron or add Thick case lid.This mode has the shortcomings that following：With the increase of the capacity and loaded switch dielectric level of transformer, case lid is long Width all drastically increases, and workload or increase case lid thickness, cause cost to increase when increasing Welder.In addition, the shape ruler of case lid Very little bigger, it is indeformable to be more difficult to guard box lid, once and case lid sinks, ponding product soil is just present with above case lid, is grown grass Phenomenon seriously affects the good appearance degree of transformer and the use of user.

Utility model content

The technical problems to be solved in the utility model is to realize to prevent at loaded switch case lid such as how inexpensive mode Sink to deforming.

In order to solve the above-mentioned technical problem, the technical solution of the utility model is to provide one kind and prevents at loaded switch case lid The structure of sinking deformation, loaded switch are arranged at the top of case lid, it is characterised in that：It is equipped on iron core high-low pressure and presss from both sides below the case lid Part, iron core high-low pressure upper clamping piece are equipped with support plate, and switch supporting plate is connected with support plate, and electrical laminated wood is arranged on switch supporting plate, electricity Work lamination wood periphery is equipped with position limiting structure, and the case lid lower surface is close in electrical laminated wood upper surface.

Preferably, the support plate is welded on the iron core high-low pressure upper clamping piece.

Preferably, the switch supporting plate is fastenedly connected with support plate by bolt, nut and washer.

Preferably, the outer rim of the electrical laminated wood length direction passes through baffle limiting.

Preferably, the outer rim of the electrical laminated wood width protects frame /V by angle steel.

Preferably, the position limiting structure includes four pieces of angle steel shield frames and two block baffles, four pieces of angle steel shield frames and two block baffles A rectangle frame is surrounded, four pieces of angle steel shield frames are respectively on four angles of rectangle frame, and two block baffles are respectively positioned at rectangle frame In two long sides；The electrical laminated wood is limited in rectangle frame.

Preferably, the switch supporting plate is steel plate.

In the utility model support construction, switch supporting plate uses electrical laminated wood using steel plate, wooden unit, and intensity height is not allowed It is yielding, it effectively prevents transformer box cover and sinks to deforming.Electrical laminated wood dielectric strength and high mechanical strength, are directly placed into In rectangle frame, since dead weight and surrounding have /V, will not move, need not other fixations, installation and its conveniently, top With the direct insulated contact of case lid.

Structure provided by the utility model overcomes the deficiencies in the prior art, can realize the independence at loaded switch case lid Support effectively prevents the case lid at loaded switch and sinks to deforming, reduces the welding quantity that traditional approach case lid strengthens iron, The space on case lid is released, while also reduces manufacture cost.

Description of the drawings

Fig. 1 is the structural front view provided in this embodiment for preventing sinking deformation at loaded switch case lid；

Fig. 2 is the structure top view provided in this embodiment for preventing sinking deformation at loaded switch case lid.

Specific embodiment

With reference to specific embodiment, the utility model is expanded on further.

Fig. 1 and Fig. 2 be respectively it is provided in this embodiment prevent at loaded switch case lid sink deformation structural front view and Top view, the structure of the deformation that prevents from sinking at loaded switch case lid on loaded switch 1, case lid 2, iron core high-low pressure by pressing from both sides The compositions such as part 3, angle steel shield frame 4, electrical laminated wood 5, support plate 6, switch supporting plate 7, baffle 8.

Loaded switch 1 is equipped with iron core high-low pressure upper clamping piece 3 mounted in 2 top of case lid, 2 lower section of case lid.On iron core high-low pressure Support plate 6 is welded on folder 3, switch supporting plate 7 is fastened with support plate 6 by the bolt, nut and washer of nigrescence.It switchs above supporting plate 7 Four pieces of angle steel shield 4 and two block baffles 8 of frame of welding, four pieces of angle steel shield 4 and two block baffles 8 of frame surround a rectangle frame, four blocks of angle steel Frame 4 is protected respectively on four angles of rectangle frame, two block baffles 8 are located in two long sides of rectangle frame.In the rectangle frame surrounded Electrical laminated wood 5 is inside put into, 2 lower surface of case lid is close in 5 upper surface of electrical laminated wood, not only plays support but also plays insulation and makees With.

In this support construction, for switch supporting plate using steel plate, wooden unit uses electrical laminated wood, intensity height do not allow it is yielding, Transformer box cover is effectively prevented to sink to deforming.

Electrical laminated wood dielectric strength and high mechanical strength, are directly placed into rectangle frame, since dead weight and surrounding have /V, Will not move, need not other fixations, installation and its conveniently, top and the direct insulated contact of case lid.

This structure is suitable for flat-top bell-jar peace top box lid type oil tank for oil immersion type transformer structure, is effectively reduced case The reinforcement iron quantity covered, releases the space on case lid, can not only prevent case lid from deforming, but also appearance looks elegant.

In addition, this structure is also applied for the no load switch adjustable transformer for conducting oneself with dignity heavier, no load switch arrangement is same to be had above Load switch layout structure.

The above is only the preferred embodiment of the utility model, in any form and substantive not to the utility model On limitation, it is noted that for those skilled in the art, do not departing from the premise of the utility model method Under, several improvement and supplement can be also made, these are improved and supplement also should be regarded as the scope of protection of the utility model.It is all ripe Professional and technical personnel is known, in the case where not departing from the spirit and scope of the utility model, when using disclosed above Technology contents and the equivalent variations of a little variation, modification and evolution made, be the utility model equivalent embodiment；Together When, the variation, modification and evolution for any equivalent variations that all substantial technologicals according to the utility model make above-described embodiment, In the range of still falling within the technical solution of the utility model.
