Description
Technical field
The utility model relates to electric power power transmission and transforming equipment technical field, particularly a kind of 35KV of being applicable to or more than 35KV voltage levels, there is compact conformation, flexible and convenient to use and economical and practical safety-type preassembled transformer station.
Background technology
Preassembled transformer station, also known as box-type substation, be one have compact conformation, Allocation transformer multiple functional, arrange convenient and use feature flexibly, both can be used as fixed electric substation, the simple type that also can be used as portable (mining) substation becomes power distribution equipment.Be widely used at present China town and country have guarantee normal power supply requirement residential neighborhoods, street, market or industrial and mining enterprises, and have the occasion such as building site, harbour, airport of provisional power demands.The basic structure of existing preassembled transformer station as shown in Figure 1, main body includes casing 1, be arranged on the hyperbaric chamber 2 in casing 1 chamber, transformer room 3, low-pressure chamber 4, and the high-tension switch cabinet GK21 be arranged in hyperbaric chamber 2, the low-tension switch cabinet DK41 being arranged on the transformer BYQ31 in transformer room 3 and being arranged in low-pressure chamber 4, the electrical input terminal of high-tension switch cabinet GK21 is installed with 35kv or more than 35KV high voltage source lead-in line joint XD211, contact between the high-voltage electrical apparatus input B311 of electric output terminals A 212 and transformer BYQ31 and be provided with the high-tension fuse 5 being positioned at hyperbaric chamber 2 and the cable or the busbar 6 that are positioned at transformer room 3.Current domestic popular preassembled transformer station divides into " order " font transformer station as shown in Figure 2 and two kinds, " product " font transformer station as shown in Figure 3 by the arrangement structure formula of hyperbaric chamber 2, transformer room 3 and low-pressure chamber 4.Their common structural feature as shown in Figure 1.In the high-tension switch cabinet GK21 in hyperbaric chamber 2, be both provided with the 35kv or more than 35KV high-tension fuse 5 that need often to detect or upgrade, be provided with again the 35kv or more than 35KV high voltage source lead-in line joint XD211 that are all in band high-tension electricity state at ordinary times simultaneously.According to China's electric utility national Specification, for the high-voltage electric system of such as 35kv electric pressure, as having the high-voltage charged body that may touch in high-tension switch cabinet cabin, then the hatch door of high-tension switch cabinet does not all allow arbitrarily to open, in order to avoid cause great human casualty accident.And the preassembled transformer station of 35KV or the 35KV above of these two kinds of versions existing, due to high-tension fuse be all in the 35kv of band high-tension electricity state or more than 35KV high voltage source lead-in line joint XD at ordinary times and coexist a Room, be obviously improper.Although high-tension fuse two ends can be made all not charged by the separating brake controlling high-tension switch cabinet GK and low-pressure chamber switch cubicle DK when overhauling or upgrade high-tension fuse, but the 35kv be positioned at below high-tension switch cabinet GK on electrical input terminal or more than 35KV high voltage source lead-in line joint XD is in the electriferous state be connected with higher level's high voltage source all the time, one actual " high-voltage charged body ", so open the hatch door of high-tension switch cabinet GK when not cutting off higher level's high-voltage suppling power, and carry out any inspection, the operation of maintenance or renewal high-tension fuse all belongs to operates against regulations, there is very large potential safety hazard.For this reason, in practical operation, need maintainer to make a special trip to a certain place and cut off higher level's high-voltage suppling power, and then open hyperbaric chamber inner high voltage switch cubicle GK hatch door, carry out site safety maintenance, not only bother but also lose time, also affect the normal power supply of using electricity system long period, except causing producing except higher maintaining cost, also certain economic loss can be brought to using electricity system; In addition, also owing to being the remote conformability operation in strange land, just in case in time or action coordinate upper inharmonious or often still can cause when making mistakes human casualty accident occurs.Therefore the preassembled transformer station general structure of existing structure form is owed rationally, maintenance is inconvenient, there is the potential safety hazard that cannot overcome, and considers all to owe desirable from practicality, economy and safety perspective.
Summary of the invention
The purpose of this utility model is the weak point existing for preassembled transformer station that will overcome existing structure form, provide a kind of structure relatively rationally, maintenance is convenient and save time, labour-saving safety-type preassembled transformer station.
Safety-type preassembled transformer station main body of the present utility model includes casing, be arranged on the hyperbaric chamber of box cavity, transformer room, low-pressure chamber, and the high-tension switch cabinet GK be arranged in hyperbaric chamber, be arranged on the transformer BYQ in transformer room, be arranged on the low-tension switch cabinet DK in low-pressure chamber, be installed in the 35kv on the electrical input terminal of high-tension switch cabinet GK or more than 35KV high voltage source lead-in line joint XD, to contact the high-tension fuse that is arranged between the electric output terminals A of high-tension switch cabinet GK and the high-voltage electrical apparatus input B of transformer BYQ and cable or busbar, be characterised in that described high-tension fuse main body is arranged in transformer room, the wall bushing of its crossing high-pressure room, one end is connected with the electric output terminals A of described high-tension switch cabinet GK, the other end is directly connected with the high-voltage electrical apparatus input B of transformer BYQ.
Based on the utility model safety-type preassembled transformer station of above-mentioned design, due to high-tension fuse main body is arranged in transformer room, high voltage source lead-in line joint XD apportion two Room be electrically connected with higher level's high-voltage suppling power, be convenient to maintenance worker can at the scene cutoff high switch cubicle GK and low-tension switch cabinet DK separating brake when can enter transformer room, directly carry out the operation overhauling or upgrade high-tension fuse, eliminating in prior art to make a special trip to a certain place cuts off higher level high-voltage suppling power and could open the door and enter the room, carry out the trouble of maintenance activity, completely eliminate the potential safety hazard that cannot overcome existing for preassembled transformer station of existing structure form, stop the generation of human casualty accident, and due between the electric output terminals A that high-tension fuse is set directly at high-tension switch cabinet GK and the high-voltage electrical apparatus input B of transformer BYQ, eliminate cable or busbar, simplify structure and the assembly technology of product, be conducive to enhancing productivity, reducing production cost and improve functional reliability.So, the utility model safety-type preassembled transformer station is compared with existing any a preassembled transformer station, obviously there is structure more scientific and reasonable, the more reliable and safety of work, keep in repair more convenient and fast and production cost, the feature that routine use cost is all low, solve exist for a long time always can not when cut off higher level's high voltage source arbitrarily enter the room, carry out a great problem detecting or upgrade high-tension fuse quickly and easily, to guaranteeing that preassembled transformer station normally runs, the normal operation of maintaining safely and fast and using electricity system can play immeasurable positive role, a large technological break-through in preassembled transformer station manufacturing technology field, market application foreground is wide.
