FZW28-12 intelligent vacuum breaker This note describes the structure, function and method of assembling column vacuum switches. FZW28 (A) -12F type outdoor vacuum circuit breaker with boundary fault detection, protection and control functions and communication functions, mounted on a 10KV overhead lines, automatic removal of single-phase ground fault isolation and automatic phase fault. Installation point of accountability applies to the demarcation point into the line of 10KV road users, but also can be applied to meet the requirements of the branch line connection. Automatic locking phase fault quickly locate the fault point automatically cut single-phase ground fault the use of environmental conditions 1) maximum ambient air temperature does not exceed 40 ℃, not limited to not more than -45 ℃; 2) the wind speed is not greater than 35m / s; 3) altitude not more than 1000m, earthquake intensity does not exceed 8 degrees; 4) Humidity: monthly average relative humidity less than 90%; daily average relative humidity less than 95%; 5) ice thickness does not exceed 10mm; 6) the installation site should be non-flammable, explosive, chemical corrosion and severe vibration place regularly; 7) neutral grounding: ungrounded, neutral point arc suppression coil grounding, neutral grounding via low resistance. FZW28-12F Outdoor boundaries vacuum load switch (VSP5-12 switch body and FDR-01 controller) with fault detection, protection and control functions and communication functions, mounted on a 10KV overhead lines, automatic removal of single-phase fault and automatic isolation phase fault. Mounting points suitable for 10KV distribution line into the line of responsibility for the user at the demarcation point, can be applied to the branch line connection to meet the requirements. Automatic locking phase fault quickly locate the fault point automatically cut single-phase fault FZW28-12F / 630-16 FZW28-12F / 630-20 FZW28-12 outdoor column vacuum load switch FZW28-12F type outdoor vacuum load switch boundaries used in the column installed on occasions, with manual and electric operation function. Switch body with the introduction of Japan's Toshiba Corp. VSP5-12, this switch is maintenance-free load switch. Vacuum interrupter and SF6 gas insulated against ground and white media. This product complies with: GB3804 "AC high voltage load switch" and GBT11022 "high-voltage switchgear and control equipment standard common technical requirements."
