15KVCông tắc ngắt kết nối gắn cựcĐược làm bằng vật liệu bền, chống ăn mòn đã được chứng minh. (Tấm thép không gỉ 304L cho tàu chiến), đảm bảo tuổi thọ dài (30 năm), công tắc ngắt tải 15KV của chúng tôi có thể thực hiện một loạt các hoạt động, với các đặc tính lý tưởng của thiết bị đỉnh cực.
Mỗi cáiGopowerCông tắc ngắt tải 15KV đã được đổ đầy khí sf6 trước khi rời khỏi nhà máy, xử lý kín. Thử nghiệm công tắc ngắt kết nối gắn cực 15 KV được thực hiện theo tiêu chuẩn IEC60265-1 (1988) GB 3804-1990.
15kv load break switch has a certain interrupting capacity because of the interrupting device, but 15 kv pole mounted disconnect switch is not as strong as the interrupting capacity of the circuit breaker, which can split the normal working current, and in the case of short circuit, he can only silently withstand the short circuit current, and if this time the manual or electric breaking may explode, so the load switch is generally used together with the current limiting fuse (load switch + fuse is not the standard configuration, and can also be used without fuse) In the event of an overload or short circuit, the circuit is broken by a fuse. In order to save costs, the load switch + fuse can replace the circuit breaker. Inquiry more pole top switches

Special attention should be paid to the voltage sensor, which must be directly fed by the 15kv load break pole mounted disconnect switch. No additional adjustment circuit can be added to the controller. The voltage signal of the switch into the test line needs to be tested separately. |
