BKHB-12 environmental protection gas insulated ring network cabinet series Its switches and main electrical components are integrated modules.

The conductive parts between the phases are solid insulated packages, shielded cable joints are used for the outward wiring, and shielded insulated busbars are used for connecting the functional units. Therefore. The safety of use is greatly improved, and the operating mechanism adopts a spring mechanism, and the mechanical life is more than 10000 times. All its operating data and equipment status can be remotely monitored and can be unattended. It is actually a power distribution device with superior performance.

The following units can be selected to form an economical and practical power supply unit in the cabinet: vacuum new circuit unit [630A, 20-25केए]; Vacuum negative cat switch unit [630, 20-25केए].

उत्पादन features:

Environmental protection: N2 or dry air is used as an insulating medium in product manufacturing to reduce greenhouse gas emissions and achieve environmental protection purposes.

अनुप्रयोगको विस्तृत श्रृंखला: कुनै विषाक्त र हानिकारक ग्याँसहरू प्रयोग गरिएको छैन, र प्रयोग वातावरणको सुरक्षा। बेसमेन्टहरू, सुरुnels, जहाजहरूमा, वा बाहिर वा भित्र। उच्च दबाव कोठाको भित्री भाग सुख्खा हावा वा नाइट्रोजनले भर्न सकिन्छ, र उच्च उचाई, कडा हावा र बालुवा, कम तापमान, गम्भीर चिसो जस्ता कठोर अवस्थाहरूमा सुरक्षित प्रयोगको लागि उपयुक्त छ, उच्च वातावरणीय सुरक्षा आवश्यकताहरू, बारम्बार अपरेशन साइटहरू, सुरक्षित र विस्फोट-प्रुफ स्थानहरू, उच्च नुन स्प्रे, र कन्डेन्सेसन सर्तहरू। पूर्ण रूपमा इन्सुलेट र पूर्ण रूपमा बन्द, पानी सेवनको छोटो अवधि पछि उपकरणहरूको लागि उपयुक्त, केहि सफा र सुख्खा उपायहरू अपनाए पछि, यो सञ्चालन जारी राख्न सक्छ।

मर्मत मुक्त: BKHB-12 वातावरणीय सुरक्षा ग्यास इन्सुलेटेड रिंग नेटवर्क क्याबिनेट श्रृंखला अपरेटिंग संयन्त्रको उच्च-भोल्टेज स्विच अंश पूर्ण रूपमा छ सिल गरिएको अवस्था, ताकि यो सफा र मर्मतबाट मुक्त हुन सक्छ, र अपरेशन र मर्मतको लागत कम गर्न सक्दछ। स्विचगेयरको एक उच्च डिग्री छ, र अनलाइन पत्ता लगाउने कार्यले उपकरणको सञ्चालनको प्रयोगकर्तालाई वास्तविक समयमा सूचित गर्दछ। यो वितरण नेटवर्कको स्वचालित रूपमा अधिक अनुकूल छ। श्रम अपरेटिंग लागत कम गर्नुहोस् र उर्जा उद्यमहरूको उत्पादन लागत कम गर्नुहोस्।

उच्च सुरक्षा: पूर्ण ईन्टरलॉकिंग र इन्टरलकिंग प्रणाली, तीन चरण पृथक विच्छेद स्पष्ट रूपमा देखिन्छ, दुरुपयोग दुर्घटनाको घटनाबाट जोगिन। SF6 ग्यासको अनुप्रयोग हटाइएको छ। इन्टर्फेज वा बहु-सर्किट छोटो सर्किटहरूबाट बच्न इन्टरफेज अलगाव संरचना सुदृढ गर्नुहोस् जसले विस्फोट दुर्घटनाहरू विस्तार गर्न वा निम्त्याउन सक्छ। विस्फोटन-प्रुफ वातावरणीय संरक्षण ग्यास क्याबिनेट भ्याकुम उर्जाको साथ भ्याकुम बुझ्ने कक्ष अपनाइएको छ, र सिल गरिएको पोल स्तम्भमा स्विचको लागि थप सुरक्षात्मक प्रदर्शन छ।

Ease of operation: the disconnect switch grounding switch has only one operating handle, no need to identify and worry about errors, when the circuit breaker is running, the operating handle of the disconnect switch grounding switch can not be operated, and there is no need for complex technical training, so that the operation becomes extremely simple and prevents operation errors.

The sealed pole is formed by epoxy resin APG process, which has excellent electrical and mechanical properties, and the sealed pole is a key component of the switch, which is both an insulating and a bearing part. At the same time, it meets the technical requirements of heat resistance, cold resistance, crack resistance, high mechanical strength, and good insulation strength.

Single cabinet structure, using general insulation busbar and cable plugging and unplugging head produced by professional cable accessory manufacturers. The switch cabinet can be closed on site and expanded at will, avoiding the inconvenience of transportation and installation caused by multi-sister closure cabinets. Of course, it can also be used to close the cabinet with the sister.

The real isolation fracture is clearly visible

The whole series of products are uniformly designed, providing a variety of cabinet types (dissolver, load switch, PT, busbar, busbar, etc.) required by users, and the shape and geometry are completely consistent.

The स्विचगेर has intelligent interfaces and sensor installation positions, which can meet the requirements of the smart grid after being equipped with intelligent equipment.

The main bus adopts standard silicone rubber dry busbar.

The disconnect switch switch adopts a three-station disconnect switch and is installed on the bus side.

Replace SF6 load switch ring network cabinet.
