RSMD-H Switchgear Testing Equipment
Type Full-Automatic SF6 Density Relay Calibrator
As switch is a high-voltage electrical apparatus widely used in the electrical system, and the operation reliability of SF6 switch has become the concern of power supply sector. SF6 gas density relay is intended for the monitoring of the SF6 gas density change in the SF6 switch body during operation, and its performance directly influences the operation safety of SF6 switch.
1) It applies 32-bit ARM single chip microcomputer and the high-speed signal processing chip of TI for detection and controlling, with a high integration degree. It is adopted with mechanical-electrical integration design, with high accuracy, good repeatability and sound reliability.
2) It is equipped with a large LCD in Chinese and rotating mouse (DIP SWITCH) human-machine interface, with easy operation, aesthetic appearance, clear parameters and status display.
3) It can realize automatic switch between pressure measurement and values under 20℃, so as to realize dynamic and automatic compensation between pressure and temperature. It can also display the pressure under the test ambient temperature and that under 20℃ as well as the environment temperature. In this way, the field calibration problem of SF6 gas density relay is solved thoroughly.
4) The whole testing is completed by apparatus automatically without manual intervention, avoiding the fussy manual gas path adjustment.
5) The testing results can be printed in the form of Chinese statement, with intelligent analysis.
6) It can store the testing results for 50 times simultaneously, and functions power failure safeguard. The former testing results could be inquired and printed at any time.
7) The calibration of SF6 gas density relay and pressure gauge could be conducted under any temperature, without thermostatic chamber.
8) It is provided with various types of transition joints, capable to conduct field calibration of most types of gas density relay without removing the relays.
9) It has low gas consumption during calibration, saving SF6 gas and testing cost, without environment pollution.
10) It functions online system clock modification.
11) It functions online system pressure modification, as well as field calibration.
12) Imported components are used as the core ones, reliable in performance.
13) It can test one set of alarm signal and two sets of blocking signal.
14) Portable and reliable, it is the selected choice for SF6 density relay calibration.
