Abstract

The utility model relates to a terminal box for testing and replacing an electric energy meter in situ. The terminal box is composed of a plug, a socket and a closing cap, wherein, the socket inside is provided with copper inserted tubes, copper contacts and springs. The terminal box can carry out experiment and measurement once the plug is plugged in; once the plug is pulled out, the socket can continue to communicate an electric source under the action of the springs. The electric source can be communicated no metter whether the closing cap is keyed in or pulled out, and the electric source needs not to be cut off, which is safe. Thus, the utility model is suitable for in situ testing and replacing various electric energy meters in high and low-voltage three-phase three-wire or three-phase four-wire systems.

Description

Electric energy displaying field converting terminal box

The utility model belongs to the terminal box technical field, is that terminal box is changed in a kind of electric energy meter field examination.

At present, generally carry out the service test terminal box in the electric system, when the site test of operation electric energy meter, need long setup time, frequently disconnect connecting conducting wire in the work, wiring error can occur and the generation accident unavoidably, change table and advance to lose quantity calculation and cause economic loss.

The purpose of this utility model provides a kind of electric energy meter field examination and changes terminal box.

The purpose of this utility model is to realize like this, it is by plug that terminal box is changed in the electric energy meter field examination, socket, capping is formed, socket is made up of base and loam cake, socket has transverse stiffener rib and vertical stiffener rib, four grooves putting spring are arranged in the base middle part, a spring is arranged in each groove, copper contact is arranged on the spring, and there is gag lever post at the base diagonal angle, on be stamped evenly distributed eight rectangular cavities and eight circular cavities, four pilot holes are arranged between circular cavity, place the copper intubate in the rectangular cavity, be connected with screw in the placement circular cavity, under rectangular cavity and the circular cavity jack is arranged by copper sheet, screw, there is the protruding lock that is connected with base the loam cake both sides, and plug one side has eight wiring positions, and opposite side has eight copper inserting columns, the gag lever post identical shaped with socket arranged between the copper inserting column, diagonal line has two gag lever posts, and the copper inserting column identical with plug arranged in the capping.Gag lever post is shorter than plug gag lever post in the capping.

The utility model is tested or when changing electric energy meter at the scene, only need to connect the electric current of standard electric energy meter, the voltage plug inserts corresponding socket respectively, promptly make things convenient for and save time again, and can guarantee operating personnel and device security, increase work efficiency greatly, housing adopts engineering plastics to form, and is high temperature resistant, corrosion-resistant, non-friable, all conducting metal plug components are all silver-plated, and small product size is little, and is in light weight, easy for installation, contact resistance is little, dielectric strength height, good mechanical property, electric current, voltage receptacle can not be pegged graft mutually, safe and reliable, be applicable to height, the site test of all kinds of electric energy meters and replacing in low pressure phase three-wire three or the three-phase four wire system can be avoided the problem that in the past occurred easily in the electric energy meter field examination changes jobs.

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

Label is described as follows among Fig. 1-Figure 12:

1 fixed screw, 2 socket bases, 3 transverse stiffener ribs, 4 vertical stiffener ribs, 5 contact framves, 6 copper contacts, 7 pilot holes, 8 springs, 9 hard point, 10 rectangular cavities, 11 circular cavities, 12 pilot holes, 13 loam cakes, 14 bronze medal plug-in units, 15 protruding locks, 16 copper sheets, 17 bronze medal intubate, 18 screws, 19 jacks, 20 screws, 21 binding posts, 22 qualifying bit bars, 23 bronze medal inserting columns, 24 bronze medal inserting columns, 25 backstays, 26 cappings, 27 backstays.

As shown in the figure, it is plug that terminal box is changed in the electric energy meter field examination, socket, capping is formed, (Fig. 2-Fig. 7) has transverse stiffener rib 3 and vertical stiffener rib 4 to socket, four grooves putting spring 8 are arranged in the base middle part, a spring 8 is arranged in each groove, spring 8 has copper contact 6, base 2 diagonal line have gag lever post 7, loam cake 13 has evenly (two rows) to arrange eight rectangular cavities 10 and eight circular cavities 11, four pilot holes 12 are arranged between circular cavity 11, place copper intubate 17 in the rectangular cavity 10, be connected with screw 18 in placing circular cavity 11 by copper sheet 16, rectangular cavity 10 and circular cavity have jack 19 11 times, screw 20, there is the protruding lock 15 that is connected with base 2 loam cake 13 both sides, and plug one side has eight binding posts 21, and opposite side has eight copper inserting columns 23, have between the copper inserting column 23 with identical shaped gag lever post 22 diagonal line of socket two limited posts 25 are arranged, copper inserting column 24 identical with plug and gag lever post 27 are arranged in the capping 26.

Base 2 is connected with loam cake 13 with protruding lock 15, during assembling, loam cake 13 is firmly depressed, and the protruding lock of loam cake 13 promptly enters in the hole of base 2.Socket is plugged capping 26 when not carrying out electrical measurement, copper inserting column 24 in the capping 26, backstay 27 just in time inserts in the jack 19 of socket 2, in the pilot hole 12, when needing to measure electric weight, open the lead sealing in the capping 26, pull up capping 26, plugging in gets final product, in order to grasp voltage, the parameter of electric current, the plug of voltage and current, socket difference are that the shape of backstay and pilot hole is different, and the plug of electric current can not insert on the voltage receptacle, and vice versa.

During on-the-spot the use, because eight terminals of eight terminals of socket loam cake and plug bond post are corresponding, referring to Figure 12, in advance the current return of standard amperemeters is concatenated into 1 joint 01 of the binding post of current plug respectively, on 2 joints, 02,3 joint, 03 terminal, 4 joints, 04 terminal is with joining the sheet short circuit; Voltage circuit respectively and receive the voltage plug binding

post

1,2,3, or 01,02, on 03 terminal, with binding post 1 joint 01,2 joint 02 of connection sheet with the voltage plug, 3 joints 03,4 joints, 04 terminal short circuit during the site test electric energy meter, will connect good electric current, voltage plug with standard scale and insert corresponding socket respectively (when testing three-phase two elements electric energy meter, current plug is only with 1 joint 01,3 joints, 03 terminal, 2 joints, 02,4 joint, 04 usefulness connection sheet short circuit).Off-test pulls the plug out of the socket, and builds capping and lead sealing.

When changing ammeter, with 1,2,3,4 ends are with the current plug that joins the sheet short circuit and do not need the voltage plug of short circuit to insert corresponding socket respectively, and this moment, electric current secondary loop short circuit voltage secondary circuit opened circuit, and removed old table, load onto Xin Biao and connect electric current, voltage on line, pull the plug out of the socket, new table operation.But on-load does not leak quantity calculation and changes table yet, promptly when being changed table outage stall, by the standard metering electric weight, treats that new table installs the back and removes standard scale.
