■ Product Overview

SF6 Switches are high-voltage electrical apparatus widely used in power systems. , SF6 The reliable operation of switches has become one of the primary concerns of power supply and distribution authorities. SF6 A gas density relay is used to monitor during operation. SF6 In the switch body SF6 An important component for detecting changes in gas density , Its performance directly affects SF6 Operational safety of the switch. On-site operation of the SF6 The gas density relay does not operate frequently. , After - After a certain period, phenomena such as sluggish operation and poor contact at the contacts often occur. , Some may also experience degraded temperature compensation performance in the density relay. , When the ambient temperature changes abruptly, it often leads to… SF6 The density relay maloperated. Therefore, DL/T596-1996 The “Regulations on Preventive Testing of Power Equipment” stipulate that… : Each SF6 The unit responsible for operating the switch shall conduct regular inspections of… SF6 The gas density relay is being calibrated. Based on actual operating conditions, for equipment in service at the site… SF6 Regular calibration of density relays and pressure gauges is also essential. This instrument employs a high-precision pressure sensor and a high sampling rate. A/D Converter, combine 32 A high-performance microprocessor can handle various… SF6 Perform performance verification of the density relay. , It can accurately measure the pressure value at the current temperature when the signal is activated, and automatically compensate for any ambient temperature effects. 20 Conversion to standard pressure at °C.
