HRMJC
SF6智能型密度继电器校验仪 |
|
| |
一、仪器概述
HRMJC型智能型SF6密度继电器校验仪，是一种智能化全自动的SF6密度继电器校验仪器。该仪器采用微机技术，能对各种SF6密度继电器进行校验，以及对SF6气体任意环境温度下的压力进行标准换算的一种便携式校验仪器，也为SF6电气产品的生产、安全运行、预试和维护提供方便。
在封闭容器中，一定温度下的SF6气体压力可代表SF6气体的密度。为了能够统一，习惯上常把20℃时SF6气体压力作为标度值。在现场校验时，在不同的环境温度下，测量的压力值都要换算成其对应20℃时的压力值，从而判断SF6密度继电器的性能。型智能型SF6密度继电器校验仪对这个过程是自动完成的，既准确，又灵活方便。本仪器除可对SF6密度继电器校验外，还具有对压力表进行校验和仪器自校的功能，这样不仅可以一机多用，还免除了仪器送检和返厂校验的难题

1) Instrument overview
HRMJC type intelligent SF6 density relay verification, it
is a kind of intelligent automatic SF6 density relay calibration
instrument. The apparatus adopts microcomputer technology,
can to all sorts of SF6 density relay, and calibrated for
SF6 gas arbitrary environmental temperature pressure standard
conversion of a portable calibration instrument, and also
for SF6 electrical products production, safe operation,
pilot test and maintenance convenience.
In closed containers, certain temperatures of SF6 gas pressure
can represent SF6 gas density. In order to be able to unity,
the custom is often the 20 ℃ SF6 gas pressure when as scale-free
values. On the spot check, in different environmental temperature,
measuring pressure value are converted to their corresponding
20 ℃ when pressure value, thus judgment SF6 density relay
performance. Type of intelligent SF6 density relay verification
of this process is completed automatically, both accurate
and agile and convenient. The instrument of SF6 density
relay except calibration outside, still have to calibrate
the instrument and the pressure gauge ZiJiao function, thus,
it can not only multi-usage, also exempted equipment inspection
and return factory calibration of difficult problems.
