Embodiment
The present invention is further clarified below in conjunction with the accompanying drawings.
Referring to Figures 1 and 2, it is a kind of to be applied to electric energy meter automatic assembly line pressure-resistant apparatus, including station computer 5,2018
Multipath server 6, Hi-pot Tester 1, current sample plate 2,2029B SECO plate 8, relay control panel 4 etc., station computer
5 are connected with 2018 multipath servers and build LAN, each separate port and Hi-pot Tester of 2018 multipath servers 6
1st, 2029B SECO plate 8,1-N epitope current samples plate 2 carry out communication connection, current sample plate 2 and 2029B SECO
Plate 8 connects AT power supplys 7, and the accessory power supply exported by AT power supplys 7 is simultaneously connected on every block of current sample plate 2 and the control of 2029B sequences
On plate 8, and there is good insulation with stage body shell.Current sample plate 2, which samples control signal, power supply signal and leakage current, to be believed
Number line is connected to relay control panel 4.The high-pressure output port of Hi-pot Tester 1 and the total high-pressure side for being connected to every piece of relay control panel 4,
The height of Hi-pot Tester 1 forces down delivery outlet whole and is connected to the low-pressure end of every piece of relay control panel 4, and with Hi-pot Tester 1
Shell be connected (avoid the low side of High voltage output in voltage-withstand test and the shell of epitope not altogether, cause ground floating, be added in table
High pressure on position is forbidden).Communication signal line and auxiliary power supply line are low frequency signals, and one must be kept with high-voltage line in cabling
Fixed safe distance (avoiding by High-frequency Interference).
Each submodule list of the LAN that the multipath server of station computer 5 and 2018 is built and each voltage-withstand test unit
Member carries out communication connection, can control multiple pressure-resistant units.
The Hi-pot Tester is 2038A Hi-pot Testers.
2029B SECO plate 8 connect tri coloured lantern 9, by tri coloured lantern 9 come indicating operating status,
As depicted in figs. 1 and 2, the current transformer 3 of every block of current sample plate 2 is arranged on the height of Hi-pot Tester 1 and forced down
Delivery outlet.
Because three-phase meter has two kinds of different access methods of direct access and mutual inductance access type, in same voltage-withstand test list
In member, with stage body, a kind of access way is distributed epitope on one side mostly.Single-phase electric energy meter and three-phase direct access electric energy meter work
Make that mode is identical with the mode of connection, due to voltage x current altogether input wiring characteristic (voltage is isolated between single-phase electric energy epitope,
It is galvanically isolated between three-phase direct epitope), as shown in figure 1, in voltage-withstand test wiring, the voltage x current of Hi-pot Tester 1
Terminal simultaneously connects and connects a high input voltage line together, and checklist auxiliary terminal and the shell the earth of checklist 10 connect together.Pressure-resistant survey
Current Voltage end is tested during examination 1min leakage currents, which whether there is superleak, to be continued to shell 4KV.Three-phase mutual inductance access electric energy meter is due to three
The input mode of phase voltage and current parameters independence, in voltage-withstand test wiring, four lines of voltage three-phase be attempted by one it is pressure-resistant
The high voltage input terminal of tester 1, three-phase current are itemized and are connected to three independent high pressure ports, and checklist auxiliary terminal is simultaneously connected to
Shell.During voltage-withstand test U over the ground, three-phase I over the ground 4KV continue 1min test, U to I, Ia to Ib, Ib to Ic, Ia to Ic2KV
Continue 1min test leakage currents whether there is superleak.
After the multipath server 6 of station computer 5 and 2018 and the communication of each voltage-withstand test subelement are normal, in voltage-withstand test,
The magnitude of voltage of the corresponding test point of the output of Hi-pot Tester 1, the high-voltage relay required by the corresponding test point of the control of current sample plate 2
Closure, high pressure are added to by the relay of closure on the terminal of corresponding test point.Under the tray bottom of electric energy meter automatic assembly line
Relay closure corresponding with the connecting line on electric energy meter shell sheet metal connection low-voltage terminal and the low-pressure end of Hi-pot Tester 1
Son communicates.High pressure is added between electric energy meter and watch case by relay closure.Current sample plate 3 passes through high pressure and electric energy meter
Insulaion resistance samples the leakage current value in epitope.Noticeable thing has two leakage current values should be noted that here.When
The leakage current value of single epitope；One is total leakage current value.During voltage-withstand test such as total leakage current superleak, Hi-pot Tester 1 can be certainly
Dynamic shut-off voltage output, buzzer are persistently alarmed.Single epitope leakage current beyond setting value do not exceed total leakage current setting value when,
Single epitope current sample plate 2 can disconnect the relay of the epitope, turn off the high pressure of the epitope.Other epitopes are not interfered with just
Often test.
During pressure test, because of the lifting of electric energy meter tray, the low pressure connecting line for causing to jack under trying to get to the heart of a matter easily is broken；Electric current
The 15K protective resistances of transformer primary are easily burnt out；Epitope signal contact thimble is easily broken off.Pay attention to correctly setting software to leak electricity
Current threshold, pressure-resistant threshold values setting etc., check and pay attention to pulling open visiting when repairing, to prevent high pressure.
