Description
Technical field
The utility model belongs to Converter Station Valve cold main pump on-bne repair special equipment field.
Background technology
Along with the continuous maturation of high voltage dc transmission technology, nationwide large area builds current conversion station, and the requisite a set of important auxiliary equipment of current conversion station is exactly valve cooling system, it can ensure that current conversion station core component converter valve operating temperature remains in confidence band, but the core component main circulation pump of valve cooling system (hereinafter referred to as: main pump) as long-term high-speed rotating equipment, its failure rate is very high, when there is main pump fault needed direct current to stop transport to overhaul, this certainly will affect sending of electricity in the past.
Valve cooling system main pump is generally a fortune one and configures for redundant, namely an other operation can be switched to when a main pump breaks down, but if do not keeped in repair in time fault water pump, system will lose redundancy, during an other main pump fault, the locking of valve group will be caused, affect electricity net safety stable, so the on-bne repair of main pump becomes trend of the times, and the technological difficulties key of main pump on-bne repair is the benefit draining to main pump place pipeline, current most current conversion station does not possess main pump on-bne repair condition, minority current conversion station is (as Chuxiong current conversion station, Pu'er current conversion station) through can meet the on-bne repair condition of main pump to the appropriate reconstruction on system superintendent road, but risk factor is high, easily cause the direct current locking because human factor causes, subject matter is as follows:
1, overhaul main pump moisturizing process by touch panel starter gate valve self small pump cold, by the external interface of small pump, the pure water in water supply tank is supplemented to emptying section, there is operation touch-screen mistiming operational risk in this, causes the locking of valve group;
2, the pure water in water supply tank or the current conversion station stock pure water general storage time very long, the pure water conductivity of long-term storage can sharply rise violently, if directly the pure water in water supply tank is supplemented to main water route, whole water-cooling generator conductivity can be caused higher, even exceed conductivity high trip value (0.7 μ s/cm) and trip after 3 seconds.
Comprehensive above analysis, if think the safe and reliable on-bne repair completing the cold main pump of valve, risk is dropped to minimum, then need a set of special water replanishing device, this device should be able to complete independently to the moisturizing of maintenance main pump pipeline, and supplementary electrical conductivity of water ensures in trip value (0.7 μ s/cm) below at least, and it is reported that current all current conversion stations still do not possess such device.
Summary of the invention
The object of this Converter Station Valve cold main pump on-bne repair moisturizing Operation Van, just in order to overcome the deficiency of the cold main pump on-bne repair of above-mentioned valve, realizes the safe and reliable on-bne repair of the cold main pump of valve.
This Converter Station Valve cold main pump on-bne repair moisturizing Operation Van is achieved by the following technical solution.
Converter Station Valve cold main pump on-bne repair moisturizing Operation Van, relate to a kind of special water supplement apparatus being specially adapted for current conversion station converter valve cooling system main pump service without power-off, feature is, the water tank comprising sliding platform and be fixed on sliding platform and soften branch road, imbibition waterflooding branch road, external moisturizing branch road with the self-loopa that water tank is connected respectively, sliding platform is also provided with operation control box; (sliding platform is used for all parts of bogey, can be dragged to any operating location easily; ) 100L pure water can be stored; Wherein self-loopa is softened branch road and is comprised and to draw from water tank and to get back to the loop of water tank: namely valve V01, self-circulating pump, valve, ion-exchanger, accurate filter and valve sequentially connect and compose; Its function is softened by self-loopa to make the pure water conductivity in water tank remain on lower value (0.7 μ s/cm) below; Imbibition waterflooding branch road adopts self priming pump, by valve, outside pure water is drawn to water tank; Route valve is propped up in external moisturizing, small pump, valve sequentially connect and compose, for carrying out supplementary pure water to pipeline during site examining and repairing; The on off control switch to self-circulating pump, small pump and self priming pump is assembled with in operation control box case, water tank is provided with conductivity transmitter, conductivity transmitter display floater is installed on operation control box, carries out real-time conductivity supervision to the pure water in water tank.The utilization of Operation Van can realize reliable moisturizing during Converter Station Valve cold main pump on-bne repair.
This Converter Station Valve cold main pump on-bne repair moisturizing Operation Van water tank adopts stainless steel, and ion-exchanger adopts stainless steel, and all connecting lines adopt stainless steel.
Current most valve cooling system cannot carry out safe and reliable on-bne repair, but the cold main pump of valve is as the core component of valve cooling system, it is again high-speed rotating equipment, its failure rate is very high, realize the on-bne repair of main pump, and ensure the fail safe of operation process, effectively can reduce direct current temporary interruption number of times, sending of effective guarantee electricity.
The design studies of Converter Station Valve cold main pump on-bne repair moisturizing Operation Van, solve the moisturizing difficult problem in on-bne repair process, and may cause think that misoperation factor is thoroughly got rid of, make main pump on-bne repair except necessary safety measure, all the other operations all complete outside system, for raising operating efficiency, safeguard work fail safe is significant.Therefore if realize the safe and reliable on-bne repair of main pump, a large blank of valve cooling system main pump on-bne repair certainly will be filled up.
The beneficial effect of this Converter Station Valve cold main pump on-bne repair moisturizing Operation Van is: convenient removable, can be dragged to any operating location and carry out operation by manpower; By simple control circuit complete operation, simple to operate; Device independently can complete pure water correction and moisturizing operation, errorless operational risk.
The utility model content is set forth further below in conjunction with Figure of description and embodiment.
