Description
Technical Field
The utility model relates to a main transformer of power station, especially main transformer core folder exempt from to dismantle protecting cover.
Background
According to the preventive test regulations of electrical equipment of hydropower stations, outdoor main transformers of the hydropower stations need to be periodically disassembled from protective covers to detect the grounding current of iron core clamps.
However, its protecting cover weight of current outdoor main transformer is very big, and it passes through fixing bolt and main transformer reciprocal anchorage, need dismantle the protecting cover when needs detect, and it overhauls very inconveniently. Moreover, the main transformer is located outdoors and can be affected by rainwater in the maintenance process, so that the problem of water seepage is caused. Furthermore, the protective cover needs to be detached during maintenance, and frequent detachment can lead to the problems of bolt sliding and the like, so that the safe operation of the main transformer is influenced.
Therefore, the protecting cover of the existing outdoor main transformer has the problems that the bolt is fixedly connected, the maintenance is inconvenient, the protecting measure is not arranged, and the fault can occur due to frequent disassembly.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a main transformer core folder exempts from to dismantle protecting cover. The utility model has the advantages of convenient maintenance, protection measures and no disassembly.
The technical scheme of the utility model: main transformer core folder exempts from to dismantle protecting cover, including locating open air main transformer and locating the protecting cover on the main transformer, its characterized in that: the protecting cover is provided with a plurality of leading-out holes; each lead-out hole is connected with a main transformer iron core clamping piece in the protecting cover through an extension line; a rain cover is arranged on the outer side of the protecting cover, and a fixing hoop is arranged on the rain cover; fastening blocks are arranged at two ends of the fixed hoop, fastening screws penetrate through the two fastening blocks, and fastening nuts are arranged at one ends of the fastening screws; one side of the rain cover is provided with a slot, and the length of the rain cover is longer than that of the protecting cover.
In the dismounting-free protective cover for the main transformer core clamp, a plurality of fixed blocks are arranged at the tail end of the rainproof cover, and each fixed block is provided with a fixed nut; the bottom of the protecting cover is provided with a thread groove corresponding to the fixing nut.
In the main transformer core clamping piece disassembly-free protective cover, the extension line is bent, and two ends of the extension line are respectively connected with the main transformer core clamping piece in the protective cover through corresponding lead-out holes; the lead-out wire is provided with a stainless steel bushing; the measurement can be carried out directly on an external lead-out wire.
Compared with the prior art, the utility model discloses through set up the lead-out hole on the protecting cover to be connected with main transformer core folder through the extension line, only need directly can detect main transformer core folder through the lead-out hole, need not to dismantle the protecting cover, its maintenance is convenient; the rain cover is additionally arranged on the protecting cover and is fastened through the fixing hoop, so that the protecting cover is prevented from being influenced by rainwater and the like, the possibility of water seepage is eliminated, and the insulating property of the protecting cover is improved; the utility model discloses the maintenance need not to dismantle the protecting cover to avoided leading to the main transformer impaired because of frequent dismantlement, guaranteed the safe operation of equipment.
Therefore, the utility model has the advantages of convenient maintenance, protection measures and no disassembly.
