Abstract
The utility model relates to a transformer neutral point rod gap combination device which consists of a neutral point isolating switch, a neutral point protective rod gap and a 'T'-shaped steel structure bracket. Before the combination device is used, the whole combination device is installed and debugged, and is compact in structure and small in volume; the combination device has good structural stability, so that an electrode is not easy to swing under the action of wind, the possibility of changes in gap distance is reduced, and the combination device is easy to install, remove and operate; the model of the neutral point isolating switch can be selected according to the requirements of users, 110 kV and 220 kV systems are matched with the isolating switches with different voltage classes, and a manual operating mechanism or an electric operating mechanism can be selected; and the steel structure mounting bracket is 'T'-shaped, integrally subjected to galvanized antiseptic treatment, and fast and convenient in field assembly.
Description
Technical field
The utility model relates to the power transmission and transforming equipment field, relates in particular to a kind of transformer neutral point rod gap protection device.
Background technology
In running, need the neutral point protection device at transformer usually.Traditional execution mode is that isolating switch and on-the-spot installation of discharging gap are made up, and has following defective: on-the-spot installation, debugging, and workload is big, long construction period; Structural stability is poor, can swing at wind-force effect bottom electrode, causes clearance distance to become big; Dismounting, installation and inconvenient operation.
Summary of the invention
Need on-the-spot Installation and Debugging, instability, be not easy to problems such as installing/dismounting and operation in order to solve traditional transformer neutral point rod gap protection device, the utility model provides a kind of transformer neutral point rod combinations of gaps device.
The technical scheme that the utility model is adopted for achieving the above object is: transformer neutral point rod combinations of gaps device, neutral point isolating switch and neutral point protection rod gap are installed on support top, the neutral point isolating switch comprises the insulation column that two bottoms are connected, each insulation column upper end is equipped with a conduction plug-in strip, and two conduction plug-in strip ends contact; Neutral point protection rod gap comprises basis, excellent gap seat, on the seat of basis, rod gap metal ground connection pillar and High-Voltage Insulation pillar are installed, on the metal ground connection pillar current transformer is installed, high voltage side electrode is installed in High-Voltage Insulation pillar upper end, and sparking electrode is installed in metal ground connection pillar upper end; Operating mechanism is fixedly installed on the support, and operating mechanism is connected with the neutral point isolating switch by connecting rod.
The neutral point lead-in wire is installed in the insulation column upper end of neutral point isolating switch, and the neutral point lead-in wire is connected with the High-Voltage Insulation pillar upper end in neutral point protection rod gap.
Described support is the T-shape steel structure support.
Transformer neutral point of the present utility model rod combinations of gaps device, before using the own Installation and Debugging of whole device good, compact conformation, volume are little; Its structural stability is good, is difficult for swinging at wind-force effect bottom electrode, and the possibility that causes clearance distance to change diminishes, and installs easily, dismantles and operation; The model of neutral point isolating switch can be selected according to user's requirement, the isolating switch of 110kV, the different electric pressures of 220kV system support, optional tennis partner's pneumatic operating mechanism of operating mechanism or motor-operating mechanism; The Steel Structure Installation support is the T font, whole zinc-plated preservative treatment, and site installation is efficient and convenient.
