15kvपोल माउंटेड डिस्कनेक्ट स्विचसिद्ध टिकाऊ, संक्षारण प्रतिरोधी सामग्री से बना है। (युद्धपोतों के लिए 304l स्टेनलेस स्टील प्लेट), एक लंबी सेवा जीवन (30 वर्ष) सुनिश्चित करें, हमारा 15kv लोड ब्रेक स्विच पोल शीर्ष उपकरण आदर्श विशेषताओं के साथ संचालन की एक श्रृंखला को पूरा कर सकता है।
प्रत्येकगोवरकारखाने छोड़ने से पहले 15kv लोड ब्रेक स्विच को SF6 गैस से भरा गया है। 15 किलोवाट पोल माउंटेड डिस्कनेक्ट स्विच परीक्षण IEC60265-1 (1988) जीबी 3804-1990 मानक के अनुसार किया गया था।
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. |
