1、smc The structure, characteristics and functions of the cable branch box
Fully enclosed, fully protected, anti-pollution, anti-corrosion, to meet the field all-weather operating conditions,Can adapt to different working environments.smcCable branch boxBelonging to floor-mounted cabinets,Small size, small footprint, if any0.65n, bring SF6The switch footprint is only1.45m; nice appearance. There will be no impact on township and city appearance.The conductor connector in the branch box adopts the crimping method, which is convenient for installation,In and out lines are flexible,In use, up to6~8 One branch incoming and outgoing lines can realize multi-channel power transmission in the community, providing a technical guarantee for entering the load center, shortening the power supply radius, and reducing line loss.TogethersmcCable branch boxIt can be equipped with power indicator, defect indicator, silicone rubber fully insulated piercing arrester, mechanical program-controlled lock, grounding switch, etc., Ensure the safety of operation maintenance processing.Collaborative cable network ring network power supply, configurableSF6 Equal ring network type load switch, under the condition of not affecting the operation of the main network, meets the maintenance requirements of some power outages, ends the maintenance of regional power outages, and reduces the scale of power outages.Together ring typesmcCable branch boxRing power supply can be terminated,Lay the foundation for future line network structure adjustment.
2、smcCable branch boxEquipment use and precautions
At present, our country produces wildsmcCable branch boxvariety, so,smcCable branch boxEquipment construction becomes very important.smcCable branch boxIs the operation method of the connection process with the cable joint equipment correct?,Whether the cable head equipment process is understood,smcCable branch boxThe order of combination of internal components and cable joint parts, whether to operate according to the manufacturer's supporting supply equipment standard instructions, etc., will directly affectsmcCable branch boxservice life and normal operation.smcCable branch box Before operation, it is necessary to check whether the grounding wire of each branch cable is firmly connected with the grounding terminal of the box. At the same time, the box shell must be directly connected to the ground network or have a significant grounding address.smcCable branch boxAfter the equipment is completed, it is necessary to test the components of the cable together in accordance with the relevant specified test standards and conditions.
3、smcCable branch boxsuccessful application in towns
Combined with the urbanization layout and development planning of forest areas, follow the principles of practicability, reliability, safety, and maintainability,existsmcCable branch boxThe following three points are mainly adopted in planning and application:The first is to comprehensively analyze real-time data on the distribution network, user data, power grid structure, equipment parameters and geographic information, so thatsmcCable branch boxmore rational distribution,Planning into- step optimization.The second is to use branch boxes with section switches and ring network switches on the main street to make the grid operation more flexible and the power supply more reliable;The third is to do a good job in testing and monitoring, strengthen follow-up testing, and timely graspsmcCable branch boxThe various technical parameters and objectives in the work are mainly to do a good job in rapid fault location, fault isolation and restoration of power supply in non-defective areas under accident conditions.
