KDSF-300 SF6 comprehensive tester is a portable high-precision comprehensive analysis instrument specially designed for detecting the gas state of SF6 electrical equipment in the power system, which is applicable to various severe or complex field and laboratory environments. The main application environments include:
HV/EHV Substation
It is used for daily patrol inspection, handover test and state maintenance of SF6 gas-filled equipment such as GIS (gas-insulated metal-enclosed switchgear), GCB (SF6 circuit breaker) and CT/PT (current/voltage transformer).
It can work stably in outdoor or indoor environment of 500kV and above substations and adapt to high temperature, low temperature, humidity change and other climate conditions.
Power plant and power transmission and distribution operation and maintenance site
Periodic gas quality evaluation shall be carried out for SF6 equipment in operation at the step-up station and regional distribution center of the power plant to prevent insulation failure caused by excessive moisture or accumulation of decomposition products.
Power equipment manufacturing and maintenance workshop
SF6 equipment such as transformer and switch cabinet shall be used to verify the gas charging quality, test the tightness and discharge of internal materials before delivery or during the overhaul process, so as to ensure that the products meet the requirements of national standards (such as GB/T 8905 and DL/T 596).
Emergency repair and fault diagnosis scene
When the equipment is abnormal (such as alarm and trip), rush to the site quickly to obtain dew point, purity and decomposition product data synchronously by taking gas once to assist in judging whether there are internal overheating, partial discharge or moisture and improve the fault locating efficiency.
Environmental protection and gas recovery management
In the process of SF6 gas recovery, purification or reuse, it is used to monitor the gas quality, ensure that the recovered gas meets the recharge standard, and help green grid construction and greenhouse gas emission reduction.
Environmental adaptability characteristics:
Wide temperature working range: it can operate normally under the ambient temperature of - 20 ℃ -+50 ℃, meeting the demand of most regions in China in four seasons;
Dust-proof and splash-proof design: good protection grade, suitable for outdoor substation dust, light rain mist and other complex working conditions;
No external air source or power supply required: built-in battery power supply, supporting independent operation on site, especially applicable to GIS bay area without power supply or limited space;
Strong anti-electromagnetic interference capability: the measurement stability can still be guaranteed under strong electromagnetic field environment (such as close to the high-voltage bus in operation).
To sum up, KDSF-300 SF6 comprehensive tester has become an indispensable core testing tool in the whole life cycle management of SF6 equipment of power system due to its multi-function integration, high reliability and strong environmental adaptability.
