Power Distribution Switch State Overhaul System Design And Implementation

Distribution network is directly related to power system and power users, the most basicpart of the distribution network of safe, reliable and stable operation is closely related topeople’s life, safe and stable operation of the distribution network to the national economy andpeople’s livelihood, state economy development the importance of self-evident. Distributionswitchgear is a wide usage in the power distribution system, one of the key equipment,accurately grasp the running state and predicting maintenance can change the powerdistribution switch passive situation, equipment failure, and later maintenance, to ensure thesafe, reliable and economic operation of distribution switchgear, improve power supplyreliability of distribution network.At this stage to switch to the more extensive management mode, the online monitoringmethod is limited, to switch the device status by operators with operation experience judgment,roughly bring safe and reliable operation of the power switch of the great hidden trouble.In this paper, based on actual status of the power distribution switch equipment, carry outbased on quantity of switchgear equipment running state of the predicting maintenance system,based on the switch equipment inspection and routine test, diagnostic test, electrified test status information, on-line monitoring, etc, and based on the field strength, and the size of the valueand development trends to make a comprehensive judgment, make for the maintenance ofpower distribution switch has timeliness and pertinence, reduce maintenance workload.Power distribution switch state overhaul system is according to the standard issued by thestate grid corporation, through inspection, routine test, diagnostic test methods for powerdistribution switch state information and statistical analysis, considering distribution switchdefect and the nature and the probability of failure, to distribution in service, this paper made acomprehensive appraisal on the performance of the switch for the power distribution switch hasprovided basis for the establishment of maintenance strategy and development system. Tostrengthen the system power distribution switch operation, maintenance, promptly eliminate thedefects and hidden trouble, improve the reliability of distribution network operation plays animportant role. System development based on B/S framework, the system level clear, easy toexpand, reasonable internal system is divided into multiple low coupling of modules, thissystem function expansion, such as the need to simply add module, task can complete systemfunction expansion. System design as far as possible to consider the needs of users, users canset according to the needs of the system running parameters to adjust the system running state.Interface is simple, convenient and quick user operations. Software mainly includes systemmanagement, parameter management information, parameter configuration, inspection, routinetest, diagnostic test, state evaluation, history test information, task list to remind, system helpmodule.Power distribution switch state overhaul system, can accurately obtain the distribution state of the switch on the quantity, scientific evaluation and maintenance requirements of thestate decision, reasonable arrangement of the state overhaul, effectively reduce the maintenancecost. If the application research, to improve the power switch on the column of master degree,the health level of equipment to reduce the maintenance cost and outage time and so on is ofgreat significance. System state of comprehensive utilization of all kinds of energy embodied inthe form of marking equipment operation condition, realize the column on the lean managementof power supply switch. To ensure the safe and reliable operation of power distribution network,the need to adapt to the current distribution network management, improve the efficiency of thepower supply enterprise is of great significance, as well as reduce power for social andeconomic losses and cause inconvenience to people’s life, improve enterprise with science andtechnology for the good social image, obtain good social benefits.
