Abstract

The invention relates to a verification device for single-phase electric energy meters and is mainly used for verifying single-phase electric energy meters in power sector. The device comprises control box bodies and meter hanging frames. Power output sources and industrial personal computers are arranged in the control box bodies. Each control box body is connected with two meter hanging frames; a testing power supply and a counting power supply in the control box body provide power for the two meter hanging frames; the industrial personal computers are used for controlling the verification process; a computer is linked with the industrial personal computers in two independent control box bodies through a router. In addition to the basic functions of metering and verification, the device which realizes carrier wave communication also has the brand new verification functions of countering test, communication detection, rate time-interval check, switching on/off test, identification authentication, secret key download and the like. Floor area is saved and meantime encryption keys are saved. The device has the characteristics of high integration level, large load, powerful functions, high reliability, lowered cost, saved labor power and improved working efficiency.

Description

The single-phase electric energy meter calibrating installation

Technical field

The present invention relates to a kind of electric energy meter calibrating apparatus, relate in particular to a kind of single-phase electric energy meter calibrating installation, belong to the Electric Application field.

Background technology

At present; Measurement centre's electrical energy meter calibration mainly contains 12 epi-position single-phase electric energy meter calibrating installations, 48 epi-positions and the novel single-phase electric energy meter calibrating installation of the automatic compression joint type of 60 epi-positions; Because the quantity of 48 epi-positions and 60 epi-position calibrating installations electric energy meter of examining and determine in the identical time is 3-4 times of old 12 epi-position calibrating installations; And 12 epi-position calibrating installations do not have calibrating functions such as dress under the key, carrier communication, authentication; Can't satisfy the verification requirement of intelligent carrier electric energy meter, cause idle unmanned use of 12 epi-position single-phase electric energy meter calibrating installations, cause the significant wastage of resource.Though 48 epi-positions and the automatic compression joint type single-phase electric energy meter of 60 epi-positions calibrating installation calibrating efficient are high; But because limited amount, it is impossible wanting to accomplish single-phase intelligent carrier electric energy meter verification task, continues to introduce new calibrating installation again; Because cost is high, also can't realize.In order to guarantee the smooth completion of annual state net carrier intelligent single-phase electric energy meter verification task, need the old calibration equipment of 12 epi-positions is carried out upgrading.

In use mainly there is following shortcoming in original 12 epi-position single-phase electric energy meter calibrating installations:

Though 1,12 epi-position calibrating installations are furnished with 485 communication interfaces, are not equipped with the carrier communication module, can't net intelligent carrier electric energy meter to state and carry out the carrier communication test;

2,12 epi-position calibrating installations do not have the key correlation module, can not net intelligent carrier electric energy meter to state and carry out global function calibratings such as authentication;

3, every 12 single-phase calibrating installation of epi-position need be equipped with one in computing machine and by a verification worker operation, it takies the resource height, and production efficiency is low, and operating cost is big.

Summary of the invention

The present invention is directed to the problem that exists in the above-mentioned prior art; Adopt split dial framework, centralized control, the existing single-phase calibrating installation of 12 epi-positions is improved, a kind of single-phase electric energy meter calibrating installation is provided; It is low to have solved in the prior art production efficiency, the problem that operating cost is big.

Technical scheme of the present invention is following:

Comprise control casing and meter hanging frame; In the control casing power output source and industrial computer are set; Each control casing links to each other with two meter hanging frames; The testing power supply of controlling in the casing provides power supply for two meter hanging frames with the power supply of having good luck, and industrial computer is controlled checking procedure, and computing machine links through router and two independent industrial computers of controlling in the casing.

Be provided with carrier module in the described control casing, realize carrier communication.

Be provided with in the described control casing and have good luck and multi-functional tester.

Advantageous effect of the present invention is following:

1, is provided with carrier module, makes calibrating installation can realize carrier communication, can carry out the carrier communication test the carrier intelligent electric energy meter.

2, be provided with and have good luck and multi-functional tester, make calibrating installation except having basic measurement verification function, also have the test of having good luck, communication detection, tariff period inspection, breaker tripping and closing test, authentication, key brand-new calibrating function such as dress down.

3,12 epi-position calibrating installations are integrated into the high integrated calibrating installation of 48 epi-positions, only need two encryption key pairs during verification carrier intelligent electric energy meter, when having practiced thrift floor area, also practiced thrift encryption key pair, solved the not enough difficult problem of encryption key pair.

4, high, the characteristics such as load is big, function is strong, reliability height of integrated level; All calibrating installation has reduced the computing machine cost of investment only by a computer control, can realize the one man operation; Greatly practiced thrift manpower, can make work efficiency improve 3 times after whole plant modification is accomplished.
