Abstract
The utility model relates to a balance installer for a mutual inductor. The balance installer is characterized in that installing holes are arranged at four corners of a positioning plate of the balance installer; a lead screw is arranged in a position of the positioning plate opposite to a primary wiring terminal; the lead screw is penetrated through a T-shaped nut on the positioning plate; and the two ends of the lead screw are respectively connected with a rotating driving mechanism and a thrust bearing box. The balance installer has the characteristics that the balance installer has simple structure and is convenient to operate and time-saving and labor-saving, the application of force is balanced and reliable, the labor intensity of assembly workers is reduced, and the damage of the primary wiring terminal due to the center-of-gravity shift of the mutual inductor in the installation process is avoided.
Description
Technical field
The utility model relates to a kind of assembling instrument transformer and uses device, is particularly suitable for the eccentric instrument transformer balance erector of primary connection terminal of upside-down mounting assembling.
Background technology
At present, the eccentric voltage transformer of installation, particularly primary connection terminal of instrument transformer is installed very difficulty in the transformer substation switch cabinet (or claiming electrical control cubicles); Because instrument transformer Heavy Weight; The eccentric design of primary connection terminal causes assembling centre-of gravity shift, makes that instrument transformer installation gravitational moment is asymmetric, uneven, and the diameter of primary connection terminal insulated column is relatively thin in addition, mechanical strength is low; During installation; Be difficult to the primary connection terminal of inverted voltage transformer is properly inserted in the switch cubicle connection contact box, cause the bending of instrument transformer primary connection terminal insulated column to damage, promptly crackle or fracture laterally appear in primary connection terminal insulated column.Especially lean on a dead lift to install; Not only waste time and energy, also can install that gravitational moment is asymmetric, uneven, the insertion position is inaccurate, not in place, cause the damage of primary connection terminal more easily because of instrument transformer; The transversal crack even the fracture of terminal post appear, and the problem of electric loose contact.The back is whole all to be dropped in the connection contact box on the switch cubicle because the primary connection terminal is installed, and phenomenons such as its damage or loose contact are difficult for coming to light, therefore in equipment puts into operation; Serious electric discharge phenomena can take place in the voltage transformer that damages; Even directly produce sub-high pressure puncture short over the ground, cause that instrument transformer burns, and can cause other power equipment and break down; Great electric operational accident takes place, and directly influences the safe operation of electric power system.
Summary of the invention
The purpose of the utility model is to provide a kind of simple in structure, easy to operate, instrument transformer balance erector that the application of force is balanced.
The technical solution of the utility model is: a kind of instrument transformer balance erector; The four jiaos of places of location-plate that it is characterized in that the balance erector are provided with installing hole; On location-plate, be provided with leading screw with the relative position of instrument transformer primary connection terminal; Leading screw passes the T type nut on the location-plate, and its two ends are connected with the thrust bearing box with rotary drive mechanism respectively.
Described location-plate is a cored slab, the weight that the hollow-core construction of location-plate can lightened plate floor, thus alleviate the weight of balance erector.
Described rotary drive mechanism is the driving handwheel or the electric control mechanism of manually control.
These practical new characteristics are: simple in structure, easy to operate, time saving and energy saving; Alleviate assembler's labour intensity; The application of force is balanced reliable, can not cause the damage of primary connection terminal because of instrument transformer centre-of gravity shift in installation process, guarantees the instrument transformer safe and reliable operation.
Description of drawings
Fig. 1 is this practical new structural representation;
Fig. 2 is the partial enlarged drawing of Fig. 1;
Fig. 3 is the structural representation of the utility model balance erector electric control mechanism.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, balance erector location-plate 4 usefulness steel plates are processed hollow sheeting, and its four jiaos places are provided with installing hole 19; On location-plate, be provided with leading screw 2; Screw mandrel should be corresponding with the position of the eccentric primary connection terminal of voltage transformer in the position of location-plate, and promptly on the extended line of eccentric primary connection terminal center line, leading screw vertically passes location-plate T type nut 3; Its upper end is connected with rotation hand wheel 1, and the lower end is connected with thrust bearing box 18.The thrust bearing box is mainly to be made up of bearing pedestal 9, bearing 7, bearing cap 6, and leading screw and bearing link together through end ring 8, see Fig. 2.If rotary drive mechanism adopts electric control mechanism, the leading screw upper end then is connected with speed changer 21, motor 22, and motor drives leading screw through gearbox and rotates, and sees Fig. 3.
Utilize the balance erector to be: to close voltage transformer 10 installation sites of opening cashier's office in a shop and be provided with 4 leads 11 with the installation process that instrument transformer is installed in transformer substation switch cabinet 14; The inverted voltage transformer of slinging also moves down along the space that is limited lead; The eccentric primary connection terminal 12 that is provided with of voltage transformer is inserted in the connection contact box 13 on the switch cubicle, realizes being electrically connected with the conductor in the connection contact box.The installing hole 17 at 15 4 jiaos of places of voltage transformer base plate is relative with lead inner bolt hole 16 respectively simultaneously.The balance erector is arranged on the voltage transformer base plate; Thrust bearing box 18 on the balance erector should be relative with the primary connection terminal position of voltage transformer; Installing hole 19 on the location-plate 4 of balance erector is relative with the installing hole on the voltage transformer base plate; With stay bolt 5 pass the installing hole on the balance erector, the installing hole on the voltage transformer base plate is threaded with the lead inner bolt hole, with balance erector, voltage transformer location.Spin balancing erector handwheel 1, screw mandrel 2 drives the thrust bearing boxes and moves down, and to voltage transformer applied thrust equably, voltage transformer moves down, and the primary connection terminal is inserted in the switch cubicle connection contact fully, and formation closely cooperates, and electric contact is reliable.After this part is installed and is finished; Whenever get next stay bolt successively by the diagonal angle order; Change a lag bolt 20 simultaneously the voltage transformer base plate is fixedly connected with lead, unload the balance erector, voltage transformer is fixedly mounted in the space of switch cubicle lead qualification.Making instrument transformer and whole pass open cabinet becomes a firmly integral body, and the external force resistance ability to function is strong, guarantees the product safety reliability service.
