A kind of test fixture for concentrator and electric energy meter communication function
Technical field
The utility model belongs to power consumer power information and gathers field, especially a kind of test fixture for concentrator and electric energy meter communication function.
Background technology
In recent years, power consumer power information acquisition system has play a part more and more important in Utilities Electric Co.'s automatic data logging, remote bill control, electricity price such as issue at the marketing work, and concentrator and electric energy meter need to communicate uniting and adjustment test as the important hardware composition part of this system before putting into operation, to guarantee that main website communicates by letter with concentrator public network and the reliability of concentrator and electric energy meter carrier communication.
At present, concentrator, electric energy meter communicate uniting and adjustment test method in laboratory is to choose concentrator and the electric energy meter of same carrier wave scheme, uses 1.5mm
2-2.5mm
2electric wire is connected voltage wiring terminal with 220V power supply, terminal address, electric meter address success Hou You main website is set and issues parameter and carry out the test of various functions.The method needs four wires connect concentrator with screw crimping and are connected with electric energy meter and with 220V power supply, require concentrator and electric energy meter to be connected in parallel on same phase circuit simultaneously, and wiring step comparatively bothers.In addition, this mode of connection is firm not, affects test result, and bare exposed conductor is many, adds that test needs zero crossing longer conduction time, exists larger potential safety hazard.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and the test fixture for concentrator and electric energy meter communication function of a kind of simple in structure, easy to use, convenient operation, high safety factor is provided.
The utility model solves its technical matters and takes following technical scheme to realize:
A test fixture for concentrator and electric energy meter communication function, is characterized in that: comprise that insulation stage body, six binding posts and three crimping handles form, and six binding post interval adjusting settings successively from left to right, two adjacent binding posts are one group; On insulation stage body, the binding post of the alternate setting of order is by being arranged on the 1.5mm in stage body
2-2.5mm
2electric wire is connected and is connected on stage body switch, and the binding post of another group sequence interval setting is arranged on 1.5mm in stage body by another
2-2.5mm
2electric wire is connected and is also connected on stage body switch, and this stage body switch connects external plug by wire.
And the insulation stage body top of described every group of binding post top is all provided with a crimping handle.
Advantage of the present utility model and good effect are:
1, this test fixture is simple in structure, practicality is easy to carry, because concentrator only needs a power supply mutually when communication function is tested with three-phase electric energy meter, do not need galvanization, therefore this frock only needs a phase voltage binding post, with respect to large test stage body, reduce the quantity of binding post, made frock more simply portable.
2, the binding post of this test fixture can move, and can select to connect concentrator and three-phase electric energy Table A, B, any phase voltage terminal of C three-phase, meets the separate requirement of energising of different carrier scheme, while therefore testing, can use flexibly.
3, this test fixture has been used three groups of connection terminals, can articulate three-phase meter, single-phase meter cooperation test during test concentrator simultaneously, makes concentrator test more system, more comprehensively.
4, the connection terminal of this test fixture was connected after switch and was connected on external plug by electric wire in stage body, and terminal has telescopic insulation sleeve, had reduced the exposed part of conductor, had increased safety coefficient.
5, this test fixture has three crimping handles, the voltage wiring terminal of concentrator and electric energy meter directly can be connected with binding post, has reduced screw compression bonded line, and this connected mode is simple and convenient, time saving and energy saving, can greatly increase work efficiency.
Accompanying drawing explanation
Fig. 1 is concentrator of the present utility model and electric energy meter communication function test fixture figure.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of test fixture for concentrator and electric energy meter communication function, comprise that insulation stage body 1, six binding posts and three crimping handles 8 form, as shown in drawings, six binding posts from left to right successively interval regulate and arrange and be respectively binding post 2, binding post 3, binding post 4, binding post 5, binding post 6 and binding post 7, six binding posts are removable, two adjacent binding posts are one group, and these three groups of binding posts all can be used for concentrator, three-phase meter and single-phase meter power supply;
On insulation stage body, binding post 2, binding post 4 and the binding post 6 of the alternate setting of order are by being arranged on the 1.5mm in stage body
2-2.5mm
2electric wire is connected and is connected on stage body switch 9, and binding post 3, binding post 5 and the binding post 7 of another group sequence interval setting are arranged on 1.5mm in stage body by another
2-2.5mm
2electric wire is connected and is also connected on stage body switch 9, and this stage body switch 9 is connected external plug 10 and carried out control system of switching on or off electricity by wire; The insulation stage body top of every group of binding post top is all provided with a crimping handle 8, and sensing chamber can make the voltage wiring terminal of concentrator, electric energy meter closely be connected with binding post.
The using method of this test fixture is as follows:
First mobile six binding posts are to the position that is applicable to concentrator, electric energy meter voltage wiring terminal, then articulate concentrator and electric energy meter, pressing crimping handle is connected firmly concentrator and electric energy meter voltage terminal and connection terminal, external plug is connected to and is exchanged on 220 power supplys, open switch, until concentrator and electric energy meter power on stable after, concentrator messaging parameter is set and by GPRS, logs in main website, manually issue the communication function that task is tested concentrator and electric energy meter item by item.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: within not departing from the spirit and scope of the utility model and claims, various replacements, variation and modification are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
