Abstract
The utility model discloses a combined electric device for large transformer neutral point protection equipment. The combined electric device comprises a transformer neutral point isolating switch, a transformer neutral point protection arrester, a transformer neutral point protection gap, a transformer neutral point current transformer and an equipment bracket, wherein the transformer neutral point isolating switch, the transformer neutral point protection arrester, the transformer neutral point protection gap, the transformer neutral point current transformer are simultaneously arranged on the equipment bracket; and a metal connecting bus is led out of a neutral point wire outlet sleeve on a transformer body and is sequentially connected with the transformer neutral point isolating switch, the transformer neutral point protection arrester, the transformer neutral point protection gap, the transformer neutral point current transformer. The combined electric device has the advantages that 1, metal connecting buses and equipment brackets among the equipment are saved, and the construction cost of the equipment is reduced; 2, the equipment arrangement is compact, the land utilization area is reduced, and the civil engineering investment is reduced; and 3, convenience is brought to the operating maintenance.
Description
Technical field
The utility model relates to a kind of electric device, particularly a kind of high-power transformer neutral point protection equipment combined electric device.
Background technology
High-power transformer neutral point protection equipment comprises transformer neutral point isolating switch, transformer neutral point protection lightning arrester, equipment such as transformer neutral point protection gap, transformer neutral point current transformer and corollary equipment fixed support; Traditional high-power transformer neutral point protection equipment adopts distributing to arrange; Each equipment independently is installed on the group equipment framework; Electrical arrangement between each equipment is stipulated according to electric pressure; Satisfy corresponding charged and maintenance distance, the transformer neutral point lead-out wire is connected with the said equipment through metallic bus bar.
The utility model content
The utility model technical problem to be solved is that a kind of integrated complete high-power transformer neutral point protection equipment combined electric device is provided.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of high-power transformer neutral point protection equipment combined electric device; Comprise transformer neutral point isolating switch, transformer neutral point protection lightning arrester, transformer neutral point protection gap; Transformer neutral point current transformer and equipment supporter; Transformer neutral point isolating switch, transformer neutral point protection lightning arrester, transformer neutral point protection gap and transformer neutral point current transformer are arranged on the equipment supporter simultaneously; Draw the metal connection bus from the neutral point outlet sleeve pipe that is positioned on the transformer body, be connected with the transformer neutral point current transformer with transformer neutral point isolating switch, transformer neutral point protection lightning arrester, transformer neutral point protection gap successively.
Said equipment supporter is a Π shape.
The beneficial effect of the utility model is:
1. traditional high-power transformer neutral point protection equipment adopts distributing to arrange that each equipment independently is installed on the group equipment framework, adopts metallic bus bar to be connected between each equipment.The utility model has been saved connection bus and the equipment frame between each equipment, has reduced equipment manufacturing cost.
2. apparatus arrangement is compact, has reduced land use area, reduces construction investment, and especially for some large hydropower stations, the high mountain gorge place is built in the power station usually in, and the apparatus arrangement place is difficulty very, and usually need cut into a mountain makes a sudden snatch, and civil engineering costs is high.
3. apparatus arrangement is compact, has reduced bus length, and the failure rate of electric equipment is reduced, and operation, maintenance and the maintenance for equipment simultaneously offers convenience.
Description of drawings
Fig. 1 is the high-power transformer neutral point protection equipment combined electric device wiring schematic diagram of the utility model.
