CHLW3-12 outdoor high-voltage SF6 recloserDetailed product description：

The CHLW3-12 outdoor high-voltage SF6 recloser is the main mode of development for rural power grid substations in unmanned substations, and a simple substation composed of 12 kV automatic reclosers is the direction of rural power grid development. Its advantages are simple structure, flexibility, easy use, and strong functionality. It is a distribution automation equipment with Chinese characteristics that has been successfully developed based on the simplified substation model planned for China's rural power grid in 2000, summarizing new development trends at home and abroad.

Function characteristics of CHLW3-12 outdoor high-voltage SF6 recloser:

a、 It can automatically protect faulty lines, identify fault states, overlap, isolate, and lock faulty lines. It is a highly intelligent switchgear that integrates control, protection, measurement, and communication. It can replace general circuit breaker relay protection control devices, eliminating the need for control screens, protection screens, and central signal screens, effectively saving comprehensive investment in substations.
b、 It can automatically execute various pre-set automatic overlapping operation sequences without excessive human intervention.
c、 The use of triple reclosing can eliminate 95% of transient faults and effectively reduce the number of power outages on the line.
d、 Effectively isolate permanent fault line sections and reduce the scope of power outages.
e、 Equipped with a remote control interface, it facilitates coordination with dispatch automation to achieve remote control, remote signaling, and telemetry functions.
f、 Fully functional and flexible installation. There are various specifications and models to meet the needs of various users.
g、 The sulfur hexafluoride automatic recloser has a pressure detection function. When the pressure is lower than the set value, it will lock and issue an alarm signal.
h、 Equipped with a self controlled power supply, and the power supply, controller, and body are integrated structures, suitable for use on various circuits.
