The intelligent box-type wind power substation comprises a transformer, a high-voltage switch cabinet, and a low-voltage switch cabinet, wherein the protection device of the transformer is made up of a gas relay, a signal thermometer and a pressure release valve; a high-voltage load switch is arranged inside the transformer and other high-voltage components are arranged inside the high-voltage switch cabinet; and a low-voltage electrical component circuit breaker and an intelligent protection component control unit are all arranged inside the low-voltage switch cabinet. The intelligent box-type wind power substation has the beneficial effects that automatic monitoring on the box-type wind power substation is realized through an automatic control unit with protection components inside the low-voltage cabinet, that no one is on duty is realized, automatic running is realized, normal operation of the power generating set is ensured, cost of running and maintenance is reduced, and then operation of the transformer can be safer, more economical and more reliable.

Description

The Intelligent wind power box-type substation
Technical field:
The utility model relates to a kind of box wind-powered electricity generation transformer station, relates in particular to a kind of Intelligent wind power box-type substation.Can be used for the various places wind energy turbine set.
Technical background:
Wind power generation is except water power, and is the most ripe, on the largest scale and the generation technology of commercialized development prospect arranged most in the regenerative resource development and use.Wind energy more and more is subject to the attention of countries in the world as a kind of regenerative resource of cleaning.Development along with wind power technology, wind-powered electricity generation combined transformer technology also obtains very fast development, have the advantages that in conjunction with the wind field transformer idle time is long, running environment is abominable, distribution is wide, operation maintenance is difficult, present wind power-used combined-type box-type transformer substation for wind power generation safeguard measure is also relatively backward, also need the operations staff to go to every day the scene to patrol and examine, in case power failure or transformer break down, be difficult to be found by manual inspection like this, this maintenance and protection to transformer is very unfavorable; And blower fan will dally and not generate electricity when breaking down, and not only can not create economic benefit, also can cause the very large wasting of resources.
Summary of the invention:
The utility model is in conjunction with the wind energy turbine set characteristics, arrange comparatively dispersion in order to solve present wind turbine generator, running environment is comparatively abominable, is difficult for being found in case have a power failure, and blower fan does not generate electricity and causes the waste of resource, and give and patrol and examine, safeguard technical problems such as bringing inconvenience, a kind of Intelligent wind power box-type substation is provided, and it comprises transformer, high-tension switch cabinet, low-tension switch cabinet, the protective device of described transformer are taken into account pressure relief valve by Buchholz relay, signal temperature and are consisted of; High voltage load switch places in the transformer, and other high pressure vigour part places in the high-tension switch cabinet; Low-voltage electrical element circuit breaker and protection vigour part intelligent control unit all place in the low-voltage cabinet.
Characteristics of the present invention and beneficial effect: Intelligent box type wind-powered electricity generation transformer station; realize automatic monitoring to box wind-powered electricity generation transformer station by adopting with the automatic control unit in protection component and the low-voltage cabinet; realized nobody hold keep, automatically the operation; namely guarantee the normal operation of generating set, reduced cost for operation maintenance again.Thereby guarantee that transformer is safer, economy, reliability service.Be embodied in:
1, adopt Buchholz relay, signal thermometer, pressure relief valve to carry tripping operation, the protection transformer body.
2, adopt intelligent control unit acceptance from the abnormal signal of Buchholz relay, signal thermometer, pressure relief valve each several part, and send signal to main control room, be implemented in remote monitoring, nobody holds and keeps.
Description of drawings:
Fig. 1 is the positive external structure schematic diagram of the utility model
Fig. 2 is Fig. 1 side internal structure schematic diagram
Fig. 3 is Fig. 1 back structural representation
Fig. 4 is the utility model electrical wiring schematic diagram
Embodiment:
Referring to Fig. 1-Fig. 3, the Intelligent wind power box-type substation, it comprises transformer 1, high-tension switch cabinet 2, low-tension switch cabinet 3, the protective device of described transformer 1 is made of Buchholz relay 4, signal thermometer 5 and pressure relief valve 6; High voltage load switch 7 places in the transformer 1, and other high pressure vigour part places in the high-tension switch cabinet; Low-voltage electrical element circuit breaker 8 and protection vigour part intelligent control unit 9 all place in the low-voltage cabinet.Wherein two kinds of versions are adopted in the protection of transformer 1:
A kind of is the protective device of described transformer 1; employing carries the version of protection vigour part at transformer body; be that Buchholz relay 4, signal thermometer 5 and pressure relief valve 6 all are with unusual tripping alarm control; send circuit breaker to by the trip signal that will send separately; accept instruction by circuit breaker and trip immediately, realize the protection to transformer.
Another kind is that the protective device of described transformer 1 adopts each status signal that sends from Buchholz relay 4, signal thermometer 5 and pressure relief valve 6 various pieces by intelligent control unit 6 acceptance; pass to main control room by Ethernet; carry out fault analysis and handling by main control room; determine trouble location according to fault status signal, the in-situ processing of sending someone.For example when high voltage load switch 7 tripping operation, normal opened contact is closed, this branch road outage, and trip signal is passed to intelligent control unit 6, passes to main control room by intelligent control unit 6 by Ethernet, realizes the protection to transformer.
Referring to Fig. 4, the electrical wiring schematic diagram, the utility model course of work is to send electricity by electrical network to transformer before the generating of blower fan end, transformer becomes 690V voltage to 35KV voltage and flows to blower fan, the blower fan starting, the anti-electricity that send is to transformer again to send the 690V electricity after the blower fan starting, and transformer flows to electrical network to voltage rising 35KV.The combined floodgate transmission process is to close first high-pressure side on-load switch G, the circuit breaker Q F of rear low-pressure side.This schematic diagram is from the high-pressure side, and lightning arrester is mainly protected the high pressure end of incoming cables, is that thunder and lightning generation electricity imports the earth to lightning wave by lightning arrester when atmospheric over-voltage is arranged.The high-tension fuse FU cut-out circuit that can fuse plays a protective role when large electric current is arranged.The ammeter of low-pressure side, voltmeter are used for showing electric current and magnitude of voltage, ammeter, must use with current transformer TA, voltmeter must use with voltage transformer pt, because the very large directly input current table of electric current in the circuit, if directly the input current table will burn, voltmeter also is can not work under high voltage as a same reason.Low-voltage circuit breaker plays the effect of deciliter circuit, all is that guard signal is passed to circuit breaker when circuit or transformer have fault, and circuit breaker trips after receiving signal, and transformer is protected.Low-pressure side lightning arrester FU4 also plays protection circuit, with the high-pressure side lightning arrester in like manner.Lighting transformer checks transformer illumination usefulness when being used in the transformer maintenance, its top circuit breaker Q F1 also is the circuit that cuts off lighting transformer.Each has just represented a slight system this Intelligent wind power box-type substation, complete independently the power transmission and transformation work.
