Abstract
The utility model provides a device for fixing a high-voltage lead of a power transformer. The device is formed by an electrical wood clamp piece (6) and iron support plates (8), and is characterized in that three groups of long slots (6.1) and three groups of square slots (6.2) are respectively arranged on one side of the electrical wood clamp piece (6) according to positions and dimensions of a three-phase high-voltage lead and a branching wire; nine shrinkable tape through holes (6.3) are arranged above the three groups of long slots (6.1) and the three groups of square slots (6.2); fixing holes (6.4) are respectively arranged on two end parts of the other side of the electrical wood clamp piece (6); the two iron support plates (8) are welded on an upper iron core clamp piece (5) according to corresponding positions of two ends of the electrical wood clamp piece (6); a fastening hole (8.1) is arranged in the middle of each iron support plate (8); two stud bolts/nuts connect the electrical wood clamp piece (6) and the iron support plates (8) into a whole through the fixing holes (6.4) and the fastening holes (8.1). The fixing device has the advantages that the energy and the materials are saved, the process is simple, and the whole device is attractive.
Description
Technical field
The utility model belongs to a kind of fixture of power transformer three-phase high-voltage lead-in wire and tap lead.
Background technology
At present, the following two kinds of modes of fixing general employing of power transformer three-phase high-voltage lead-in wire and tap lead: the one, with two blocks of electrician's wood, one another piece is not slotted according to the size gone between and size fluting, utilizes bolt and nut and packing ring clamping lead-in wire.Its shortcoming is: 1. wasted valuable electrician's timber, improved cost; While 2. taking a lot of work, reduced operating efficiency; If 3. the long ，Qi of electrician's wood clamp spare center also needs the bakelite bolt and nut to fix.The 2nd, adopt insulating board, according to the size gone between and size perforate, lead-in wire is carried out to planar and fix, need three insulation boards to use separately.Its deficiency is 1. axially can not fix, and is free state, when transporting or rocking, may cause the junction fracture of lead-in wire and winding; 2. the insulating board cost is high, and utilance is low, processed complex, and every fixed head needs the several piece insulating board to complete with hot pressing through gluing is bonding, power consumption; 3. want multiplex several bolt and nut packing rings.
Summary of the invention
For shortcoming or the deficiency of above-mentioned similar technology, the purpose of this utility model is to provide high, the effective power transformer high-voltage connection fixture of a kind of efficiency.
The technical solution of the utility model is: it is comprised of electrician's wood clamp spare and iron support plate, one side of electrician's wood clamp spare respectively has 3 group leader's grooves and 3 prescription grooves according to position and the size of three-phase high-voltage lead-in wire and minute wiring, the top of 3 group leader's grooves and 3 prescription grooves has 9 tightening belt perforation altogether, and the opposite side both ends of electrician's wood clamp spare respectively have fixing hole; 2 iron support plates are welded on the upper core folder according to electrician's wood clamp spare end positions, in the middle of the iron support plate, have fastener hole; 2 stud nuts are connected as a single entity electrician's wooden splint and iron support plate by fixing hole and fastener hole.
The utility model has the advantages that: 1. simple in structure, easy to use, winding is stressed evenly; 2. energy-saving material, efficiency is high; 3. simply applicable, safe and reliable; 4. production cost reduces, easy for installation.

Embodiment
Now by reference to the accompanying drawings, technology contents of the present utility model is carried out to detailed description.
The utility model is comprised of electrician's wood clamp spare 6 and iron support plate 8, one side of electrician's wood clamp spare 6 respectively has 3 group leader's grooves 6.1 and 3 prescription grooves 6.2 according to position and the size of three-phase high-voltage lead-in wire and minute wiring, the top of 3 group leader's grooves 6.1 and 3 prescription grooves 6.2 has 9 tightening belt perforation 6.3 altogether, and the opposite side both ends of electrician's wood clamp spare 6 respectively have fixing hole 6.4.2 iron support plates 8 are welded on upper core folder 5 according to electrician's wood clamp spare 6 relevant positions, two ends, in the middle of iron support plate 8, have fastener hole 8.1.2 stud nuts are connected as a single entity electrician's wooden splint 6 and iron support plate 8 by fixing hole 6.4 and fastener hole 8.1.
During enforcement, first high-voltage connection and tap lead are wrapped to secondary insulation 3, then be wound around with tightening belt 7; Elongated slot 6.1 and square groove 6.2 that high-voltage connection after being wound around and tap lead are placed in respectively to electrician's wood clamp spare 6, and utilize tightening belt perforation 6.3 to cause tightening belt 7 head and the tail fast knots to be connected; Finally with the stud nut, by fixing hole 6.4 and fastener hole 8.1, electrician's wood clamp spare 6 and iron support plate 8 are connected as a single entity.
