Abstract
The invention discloses a supporting bracket for an inserting piece. The supporting bracket comprises a platelike bracket base body, wherein the bracket base body comprises two mounting supporting plates and a web plate connected between the two mounting supporting plates; the bracket base body is I-shaped; supporting guide grooves for mounting the inserting piece are formed in two sides, deviated from the web plate, of the mounting supporting plate respectively; and openings of the supporting guide grooves face the web plate. Compared with the prior art, the supporting guide grooves with the openings facing the web plate are formed in the supporting bracket for the inserting piece, the inserting piece is mounted in the supporting guide grooves, a secondary winding is mounted below the supporting bracket for the inserting piece, and the supporting bracket, the inserting piece and the secondary winding are put in a mold for pouring epoxy resin. When the epoxy resin is cured and shrunk, the epoxy resin drives the inserting piece to move towards the central part along the supporting guide grooves, so that relative movement is not generated between the epoxy resin and the inserting piece, and the epoxy resin on the periphery of the inserting piece does not crack.
Description
Technical field
The present invention relates to transformer technical field, particularly relate to a kind of inserts and support support.
Background technology
Transformer is as one of supporting critical elements of electrical equipment, including secondary coil, mainly gives measuring instrument, instrument or protection device transmission information.At present, most of transformers are in process of production, fixing all employing of secondary coil firmly bundlees mode with fixed support, and be connected by welding manner between fixed support and the inserts of transformer, time die-filling, secondary coil is fixed on mould by inserts together with fixed support, and then casting epoxy resin makes three be fixed together.As illustrated in fig. 1 and 2,1 is inserts, and 2 is support, and 3 is secondary coil.Inserts 1 is standard product, is provided with twice annular groove 11.nullSupport 2 includes rest body 21 and two collateral faggings 22，Rest body 21 is substantially in I shape，The mid portion both sides of support 2 respectively connect side gripper shoe 22，For increasing the contact area of supporting structure 2 and secondary coil，Collateral fagging 22 is at a certain angle with rest body 21 downward-sloping，Rest body 21 rear and front end is each provided with two support guide grooves 23，Support guide groove 23 opening on rest body 21 front end is towards front end、Support guide groove 23 opening on rear end is towards rear end，Support guide groove 23 is used for installing inserts 1，The annular groove 11 of inserts 1 is embedded in support guide groove 23，The support guide groove 23 arranged on rest body 21 plays the fixing support to inserts 1 and position-limiting action，This structure is in transformer later stage forming process，Owing to epoxy resin is to center cure shrinkage，And inserts 1 by support guide groove 23 is spacing can not be to central motion，Epoxy resin around inserts 1 is understanding the stop by inserts 1 during the cure shrinkage of center，Inserts 1 periphery epoxy resin cracking situation the most often occurs，This is accomplished by repairing product in the later stage，Add manufacturing cost，Also product quality is affected.
Summary of the invention
It is an object of the invention to provide a kind of inserts and support support, with the problem solving to use existing supporting structure to cause the epoxy resin of inserts periphery to ftracture.
For achieving the above object, inserts of the present invention supports the technical scheme of support: inserts supports support and includes the rest body of tabular, described rest body includes that two are installed gripper shoe and are connected to two webs installed between gripper shoe, described rest body is I shape, being provided with the support guide groove for installing inserts on the both sides of the described installation gripper shoe described web of deviation, described support guide channel opening is towards described web.
Each described support guide channel opening is towards identical with the epoxy resin cure shrinkage direction at its position.
Described support guide groove be shaped as U-shaped.
Described inserts supports support and also includes symmetrically arranged for contacting fixing collateral fagging with Secondary Winding, and described collateral fagging is angled with described rest body downward-sloping.
Described collateral fagging is symmetricly set in rest body web both sides.
The invention has the beneficial effects as follows: inserts supports support and is provided with the opening support guide groove towards web, and inserts is installed in support guide groove, inserts supports and is provided with Secondary Winding below support, and three puts into casting epoxy resin in mould.When epoxy resin cure shrinks, epoxy resin drives inserts to move along support guide groove to core, does not therefore produce relative motion between epoxy resin and inserts, and the epoxy resin of inserts periphery does not haves the situation of cracking.
Accompanying drawing explanation

Fig. 2 is the top view of fixing rack structure in Fig. 1；
Fig. 3 is the structural representation that inserts of the present invention supports support specific embodiment.
Detailed description of the invention
The inserts of the present invention supports the specific embodiment of support, as shown in Figure 3.Fig. 1 shows that inserts supports the use state diagram of support, and 1 is inserts, and 2 is support, and 3 is Secondary Winding, and inserts 1 is provided with annular groove 11.Inserts supports support 2 and includes rest body 21, two 22, four support guide grooves 241 of collateral fagging.Rest body 21 includes that two are installed gripper shoe 24 and are connected to two webs installed between gripper shoe 24, its shape is substantially in I shape, it is provided with support guide groove 241 in the installation gripper shoe 24 extended about rest body 21 two ends, support guide groove 241 be shaped as U-shaped, the opening of four support guide grooves 241 is towards web and consistent with the epoxy resin cure shrinkage direction at its position.The web lateral symmetry of rest body 21 is provided with collateral fagging 22, the contact area of support 2 and Secondary Winding 3 is supported for increasing inserts, making Secondary Winding 3 and inserts support support 2 fixing more firm, collateral fagging 22 is at a certain angle with rest body 21 downward-sloping.
Inserts supports support 2 in use, first Secondary Winding 3 is positioned over inserts and supports the lower section of support 2, the axis direction of Secondary Winding 3 is parallel with the direction, web place of rest body 21, and the periphery of Secondary Winding and two collateral faggings 22 contact, the most again will both firmly bindings.Inserts 1 is arranged in support guide groove 241, and the distance between support guide groove 241 dual-side is consistent with the diameter at inserts 1 annular groove 11, and inserts 1 can move to core in support guide groove 241.After inserts 1 installs, three is put into casting epoxy resin in mould, it is separable that inserts 1 and inserts support support 2, when epoxy resin is to center cure shrinkage, epoxy resin can drive inserts 1 to move to center, owing to the opening direction of support guide groove 241 and the cure shrinkage direction of epoxy resin are consistent, epoxy resin can drive inserts 1 to move along the side of support guide groove 241 to center, relative motion is not had between epoxy resin and inserts 1, therefore, the epoxy resin of inserts 1 periphery does not haves the situation of cracking.
In other embodiments, collateral fagging includes that the arc mated with Secondary Winding cylindrical, arc contact with Secondary Winding cylindrical coupling, make both connections more firm.
