Description
Technical field
The utility model relates to the installing area of ultra-high voltage converter station converter valve, relates in particular to a kind of ± 800kV ultra-high voltage converter station converter valve monitoring control device is installed.
Background technology
At present, the coal resource distribution of China 76% is in the north and the northwestward; 80% hydraulic power potentials is distributed in the west and south; Overwhelming majority land wind energy, solar energy resources are distributed in the northwestward.More than 70% energy demand simultaneously but concentrates on middle part, east.At load center, build thermal power plant, Coal Transport, environmental capacity are all a problem, and existing electrical network cannot be realized large-capacity power conveying, therefore, builds extra-high voltage electric power passage and becomes unique selection.Extra-high voltage direct-current transmission is for remote or overlength distance transmission of electricity, because its relatively traditional ac transmission is more economical, be applicable to long distance, large capacity transmission, have line loss low, transmission obvious energy conservation, the features such as circuit corridor is narrow, occupation of land is few, and the method for operation is flexible, governing speed is fast, reliable.
Ha Minan-Zhengzhou ± 800kV extra-high voltage direct-current transmission engineering is that DC transmission engineering electric pressure is the highest in the world at present, transmission capacity is maximum (transmission power 8000MW), the DC transmission engineering of fed distance the longest (total track length 2210km).Rated direct voltage ± 800kV, rated direct current 5000A.This project adopts at present state-of-the-art 6 inch thyristors in the world, and this is also the nucleus equipment of direct current transportation, and installation and operation is high to environmental requirement, ℃-25 ℃, temperature+10, the valve Room; Relative humidity is less than 60%; Air is through three-stage filtration, and 24 hourly averages of PM2.5 numerical value should be less than 75(μ g/m3).
In converter valve installation in the past, although equipment manufacturers have proposed strict demand to environment, but unit in charge of construction did not monitor environment in the construction stage, still according to conventional way, construct, mainly rely on aspect clean in the valve Room and sweep the floor, wash and mopped floor.In work progress, the shutoff of the valve Room just becomes installation progress according to the change of current and carries out shutoff, and the air-conditioning system being equipped with is blown in the valve Room according to the temperature of setting.
Aspect construction management, safety technique is told somebody what one's real intentions are and mainly with mode word, is carried out, and takes passages the partial content in arrangement and method for construction, and after workmen accepts to tell somebody what one's real intentions are, on the record of telling somebody what one's real intentions are, signature is confirmed.In daily station class meeting, mainly take at the bottom of construction responsible official's an casual acquaintance as main, workmen mainly be take and is listened as main.In work progress management, construction responsible official and security official carry out safety supervision from two angles, and it is main that physical inspection afterwards is mainly leaned in quality check.
When converter valve components lifts, workmen ties assembly by chain or suspender belt, with electric block lifting subassembly, installs.
The shortcoming of current construction and installation is as described below:
(1), according to conventional method, do the valve Room when clean, sweep the floor and can in the valve Room, kick up a dust, affect the cleanliness factor of converter valve and assembly, washing mops floor can increase the relative humidity in the valve Room, affects the quality of converter valve.
(2), in converter valve installation process, air-conditioning system continues to send into pure air in the valve Room, if suitable shutoff is not carried out in the valve Room, outdoor dust will enter the valve Room from converter transformer sleeve mounting hole, affects the cleanliness in the valve Room.In the valve Room, without atmospheric pressure monitoring arrangement, air-conditioning amount cannot regulate according to situation in the valve Room, can not guarantee that outdoor dust does not enter the valve Room.
(3), in construction management, safe construction is primary, the main points of safety management are mainly people's unsafe acts and the unsafe condition of thing, the class meeting of daily station is the major way to people's management, and it is habitual tired easily to allow people produce at the bottom of conventional oral and pen friends, do not have the effect of telling somebody what one's real intentions are.
(4), in converter valve installation, high-rise working is many, and construction responsible official and security official mainly guard on ground, have very large dead band, visual angle, cannot control condition of construction comprehensively.
(5), controlling aspect installation quality, the method for conventional postmortem cannot be found hiding mass defect, is also inconvenient to carry out crash analysis while going wrong.
(6), when using electric block to carry out the lifting of assembly, workmen generally lifts by crane electric block at full speed, easily occurs rocking of overload power and assembly, may occur looseningly or crooked after chain or suspender belt colligation in lifting process, causes security incident.
