Description

A kind of training set for electric power meter wiring

Technical field

This utility model relates to Electric Energy Metering Technology field, is specifically related to a kind of training for electric power meter wiring Device.

Background technology

Three-phase and four-line electric power meter is currently power supply enterprise's important device for electric energy metrical, and this device specifically wraps Include: it is some that three-phase and four-line intelligent meter one, current transformer three, busbar, combined connection box and secondary connect wire.With The raising for electric energy metrical accuracy requirement of the development of economic society and power consumer, grasp the wiring of electric power meter Method has become as the professional skill that work about electric power person is indispensable, and the most therefore the training of electric power meter wiring meets the tendency And give birth to.

Metering device used by production scene designs for power consumer, as long as work about electric power personnel will according to specification Each electrical part is fixed on device, it is not necessary to each device of mounting or dismounting repeatedly.The training dress that the most each training unit uses Put identical with the electric power meter that power generation scene is used.Owing to during training, student needs on training set many Secondary mounting or dismounting current transformer and wiring thereof, cause the terminal above current transformer often to damage, it is impossible to be continuing with.In order to really Protecting training quality, training unit can only constantly change current transformer, causes serious economy to bear if things go on like this to training unit Load and wasting phenomenon, also occupy the substantial amounts of training time when changing current transformer.

Summary of the invention

Often damage for current transformer terminal in current training set, training unit need constantly to change transformer with Meeting the phenomenon of training requirement, the purpose of this utility model is, it is provided that a kind of new electricity that need not change current transformer The training set of energy metering device wiring.

In order to realize above-mentioned task, this utility model takes following solution:

A kind of training set for electric power meter wiring, including training cabinet, in training cashier's office in a shop equipped with three-phase and four-line Intelligent meter, three current transformers, combined connection box, busbars, wherein, after a described busbar is arranged on training cabinet Face, current transformer is fixed on a busbar；It is characterized in that, be additionally provided with line bank in Current Transformer Secondary side, should Line bank is connected with Current Transformer Secondary side by fixed plate, the connection wire of Current Transformer Secondary by line bank with Current Transformer Secondary side button is connected, then is connected with three-phase and four-line intelligent meter by combined connection box.

Other features of the present utility model are:

Described line bank has three, and each line bank has three screw holes.

Described line bank uses thickness to be 4mm copper material.

Described fixed plate is insulation board.

Training set for electric power meter wiring of the present utility model, by Current Transformer Secondary side terminal On install line bank additional, it is to avoid secondary side connect wire be joined directly together with Current Transformer Secondary side terminal.Current Transformer Secondary After installing line bank additional on side terminal, when student's mounting or dismounting connect wire, only need to carry out on line bank, be not required to twist transformer two Secondary side terminal, the most only need to change line bank if any damaging, thus effectively prevent and frequently change current transformer.Thus effectively subtract Lack training cost expenditure, made training the most feasible.

Accompanying drawing explanation

Fig. 1 is installation electric current after the training cabinet in the training set of electric power meter wiring of the present utility model Transformer secondary and install line bank schematic diagram additional.

Labelling in figure represents respectively: 1, training cabinet, 2, busbar, 3, current transformer, 4, fixed plate, 5, wiring Row.

Below in conjunction with accompanying drawing, this utility model is described in further detail.

Detailed description of the invention

See Fig. 1, this gives a kind of training set for electric power meter wiring, including training cabinet 1, Equipped with three-phase and four-line intelligent meter, three current transformers, combined connection box, busbars 2 on training cabinet 1, wherein, described One time busbar 2 is arranged on after training cabinet 1, and current transformer 3 is fixed on a busbar 2；At current transformer 2 secondary side also Being provided with line bank 5, this line bank 5 is connected with current transformer 3 secondary side by fixed plate 4, current transformer 3 two times Connect wire to be connected with current transformer 3 secondary side terminal by line bank 5, then by combined connection box and three-phase and four-line intelligence Can be connected by table.

In the present embodiment, line bank 5 has three, and using thickness is 4mm copper material, and each line bank 5 has three Screw hole.Fixed plate 4 is insulation board.

When training set uses, the three-phase and four-line intelligent meter before training cabinet 1, the installation method of combined connection box are existing with production The installation method of the electric power meter in place is identical, and (not shown in figure, concrete installation method enters with reference to national regulation OK)；The mode of connection of electric power meter used by the current transformer 3 secondary side wiring installed after training cabinet 1 and production scene Difference, electric current, voltage terminal at current transformer 3 secondary side install three line banks 5 respectively additional, and are consolidated by three line banks 5 It is scheduled on insulation board 4.Having three screw holes on the most each line bank 5, a screw hole of upper end is responsible for and current transformer 3 Secondary side voltage (electric current) terminal is connected；Middle screw hole is for being connected line bank 5 with insulation board, to prevent training Student causes line bank to rock when practising wiring, causes the faults such as short circuit；The screw hole of lower end is responsible for current transformer 3 two times Connect the connection of wire.

According to this design, each secondary connects wire and realizes the company with current transformer 3 secondary side by line bank 5 Connecing, if to practise number of times more for student, cause the screw hole on line bank 5 and loosen, what training unit also only need to more renew connects Line row 5, without frequently changing current transformer 3.

Use the above-mentioned training set for electric power meter wiring, effectively prevent Current Transformer Secondary side button Often damaging, training unit the most often changes current transformer, thus effectively reduces training cost expenditure, makes training The most feasible.

The line bank that installs additional in the present embodiment, insulation board material wide material sources, construction is simple, with low cost, is prevented effectively from Current Transformer Secondary side button is often damaged, and makes the training unit the most often change transformer, is a kind of practical function Preferably training set.
