Introduction
This procedure is based on JJF1002-2010 "national measurement procedures for the preparation of rules" preparation.
This procedure is based on JJG 795-2004 "withstand voltage tester verification procedures" based on the revision. And JJG
795-2004 compared to the rules in addition to editorial changes, the technical part of the changes are as follows.
--- AC and DC output voltage base value error to set the voltage error;
--- increase the display voltage error test;
--- Breakdown alarm current base value error to break the alarm preset current error;
--- increase the leakage current indication error test;
--- clear the breakdown of the alarm current preset error of the test point;
--- modified the output capacity of the pressure meter verification method;
- the maximum allowable error and the verification point of the output voltage duration (hold)
--- modified functional requirements;
--- Added terminology.
The previous versions of this order are released as follows.
--- JJG 795-2004.
Test procedure for withstand voltage tester
1 Scope
This procedure applies to the maximum output voltage of not more than 15kV withstand voltage tester (hereinafter referred to as pressure meter), package
Including digital display and pointer to indicate the exchange (frequency), DC and AC-DC withstand voltage tester for the first time, follow-up
Check and check in use. Also applies to insulation pressure tester, leakage pressure tester and other safety performance tester
Of the withstand voltage part of the test.
This procedure does not apply to the pulse voltage or audio voltage output tester, wire and cable with a spark machine, electromagnetic compatibility
Testing of high pressure test equipment.
2 reference file
This procedure refers to the following documents.
GB 4793.1 Safety requirements for electrical equipment for measurement, control and laboratory use - Part 1. General requirements
For dated references, only the dated edition applies to this rule; references that are not dated
, The latest version (including all amendments) applies to this procedure.
3 terms and units of measurement
Leakage current
The output voltage of the withstand voltage gauge through the insulation or distribution of the parameters of the current generated by the impedance.
Note. Some of the pressure meter can show the leakage current value.
3.2 Breakdown Alarm Preset Current breakdownwarningcurrent
In the pressure meter set on the leakage current threshold, when the leakage current is greater than the value, the pressure gauge will automatically cut off the output
Voltage and send an alarm signal.
3.3 Output Voltage Hold (Hold) Time
The voltage experienced by the voltage regulator during the stabilization phase does not include the time the voltage rises and falls.
3.4 nominal capacity nominalcapacity
Voltage of the voltage limit of the maximum range of full value UH and the maximum breakdown alarm current IH of the product, with PH said.
4 Overview
The pressure tester is used to detect and test the electrical resistance of various electrical equipment, insulation materials and insulation structures.
The instrument.
Pressure gauge according to the display can be divided into pointer and digital, according to the output voltage generation and regulation can be divided
For the autostable voltage regulator and programmable voltage regulator, according to the breakdown current alarm can be divided into voltage comparator based on the hardware limit
Alarm and software-based software overrun alarm.
Autotransformer pressure regulator through the knob to adjust the variable ratio of the autotransformer to change the input voltage of the step-up transformer, thus
Adjust the output voltage. Programmable voltage regulator by micro-controller (single-chip) control generated sine wave signal, and then through the power
