Abstract

A Verification of Measuring Current Transformer secondary connection servicing unit, comprises casing, and the left side of described casing is provided with input terminal, and right side is provided with two above outlet terminals, and upside is provided with the switch equating with outlet terminal quantity; Each outlet terminal is connected to bus by a switch, and bus is connected to input terminal.The utility model has reduced the calibrating time of Verification of Measuring Current Transformer, has improved testing efficiency.

Description

A kind of Verification of Measuring Current Transformer secondary connection servicing unit
Technical field
The utility model relates to power electric meter field tests, is specifically related to a kind of Verification of Measuring Current Transformer secondary connection servicing unit.
Background technology
Verification of Measuring Current Transformer is compulsory verification metering outfit, according to JJG313-2010 < < Verification of Measuring Current Transformer > > vertification regulation regulation, the Verification of Measuring Current Transformer of newly purchasing and examining and determine full 2 years must compulsory verification.Verification of Measuring Current Transformer is as transmission of quantity value instrument, and its no-load voltage ratio must broad covered area, and the no-load voltage ratio of Verification of Measuring Current Transformer generally has more than 30, during calibrating, must examine and determine each no-load voltage ratio.Verification system is mainly comprised of calibrating operator's console (comprising tester, load box), standard current transformer, tested current transformer, standard current transformer and tested current transformer are from examining and determine operator's console more than 4 meters, no-load voltage ratio of every calibrating, staff need enter in safe fence standard current transformer and tested current transformer are carried out to thread-changing from operator's console, cause examining and determine inefficiency, the Verification of Measuring Current Transformer of 30 no-load voltage ratios of calibrating needs more than 2 hours under normal circumstances, length consuming time.
Utility model content
The utility model provides a kind of Verification of Measuring Current Transformer secondary connection servicing unit, during test, disposablely completes wiring, needn't thread-changing in test process, and the used time is short, and efficiency is high.
The technical scheme that the utility model adopts is: a kind of Verification of Measuring Current Transformer secondary connection servicing unit, comprise casing, the left side of described casing is provided with input terminal, and right side is provided with two above outlet terminals, and upside is provided with the switch equating with outlet terminal quantity; Each outlet terminal is connected to bus by a switch, and bus is connected to input terminal.
The beneficial effects of the utility model are: reduced the thread-changing operation in test process, the test used time is short, and efficiency is high.
Accompanying drawing explanation
Fig. 1 is a kind of Verification of Measuring Current Transformer secondary connection servicing unit schematic diagram.
In figure: 1-casing; 2-input terminal; 3-bus; 4-switch; 5-outlet terminal.
Embodiment
Embodiment: as shown in Figure 1, a kind of Verification of Measuring Current Transformer secondary connection of the utility model servicing unit comprises casing 1, the left side of described casing 1 is provided with input terminal 2, and right side is provided with two above outlet terminals 5, and upside is provided with the switch 4 equating with outlet terminal 5 quantity; Each outlet terminal 5 is linked bus 3 by a switch 4, and bus 3 is connected to input terminal 2.
When this Verification of Measuring Current Transformer secondary connection servicing unit is installed, input terminal 2 is connected to tester, and each outlet terminal 5 is connected respectively on the connection terminal that tested current transformer is corresponding.Standard current transformer has adopted same mode with being connected of tester, be to utilize another Verification of Measuring Current Transformer secondary connection servicing unit, this device input terminal 2 is connected to tester, and its each outlet terminal 5 is connected respectively on the connection terminal that standard current transformer is corresponding.During test, only need will need tested current transformer connecting terminal and the corresponding switch 4 of standard current transformer connection terminal of conducting closed, thereby realized the conducting between the tested current transformer of strain ratio and standard current transformer, and then test.By the present embodiment, also can know, need only the set outlet terminal 5 of this Verification of Measuring Current Transformer secondary connection servicing unit abundant, can meet the more Verification of Measuring Current Transformer of connection terminal and use.
Adopt after the utility model, reduced the calibrating time of Verification of Measuring Current Transformer, improved testing efficiency.
