Description
Technical field
The present invention relates to air-conditioning system operation control technology field more particularly to a kind of converter station valve hall air-conditioning system are automatic
Switching method.
Background technique
Usual converter station is designed with multiple valve halls, and the multiple a change of current valve towers of arrangement, valve hall air-conditioning system are in each valve hall
The important ancillary equipment of DC converter station safe and stable operation, the major function of valve hall air-conditioning system have：
1) when direct current system operates normally, converter valve can generate a large amount of heat, although valve cooling system has been taken away greatly
Partial heat, but converter valve will distribute very big heat to valve hall；In order to guarantee that the normal operation of electrical equipment, valve hall are necessary
Cool down；And in winter, when converter valve is stopped transport and outdoor temperature is again very low, need to be promoted room temperature to guarantee electrical equipment
It is not damaged by frost；
2) in order to which flashover does not occur when guaranteeing converter valve operation, the relative humidity in valve hall is needed to carry out centainly
Control；
3) outdoor dust enters valve hall in order to prevent, needs to keep clean in valve hall, also needs to maintain micro-positive pressure in valve hall.
Air-treatment unit and water circulating pump in converter station valve hall air-conditioning system are divided into A, B two systems, a work one
It is standby.If single set system long-play will appear the event such as motor bearings over-heating erosion, belt fracture, water circulating pump percolating water
Barrier increases maintenance workload, reduces service life of equipment, and then will cause valve hall air-conditioning system job insecurity.
To avoid set of system premature breakdown due to long-play, periodically two unit air-conditioner units must be switched over.
The air-conditioner set of most domestic converter station valve hall puts into operation the time all relatively early at present, and automation degree of equipment is not high, every time
It requires manually to switch.Manual handover operation increases the quantity of required plant maintenance operation personnel and the inspection frequency of personnel
It is secondary and cumbersome；As the operation time limit increases, greatly increase O&M cost, can also because caused by manual operation is improper equipment damage
It is bad.

When switching, the runing time of 1 group of air-treatment unit being in working condition automatically to switching is recorded, set runing time as
100~200 hours, after the separate run times of air-treatment unit reach setting runing time, switching command was assigned to double
Automatic power switch a pair of air-treatment unit automatically switches, while assigning switching command to double power supply automatic switching switch
Two pairs of water circulating pumps synchronize switching；
3) the power control terminal difference of A group air-treatment unit, B group air-treatment unit, water circulating pump A, water circulating pump B
If manual switching button, and link between each manual switching button, i.e., B group when A group air-treatment unit is switched to working condition
Air-treatment unit is automatically stopped operation, while water circulating pump A starts, and water circulating pump B stops；Switch the equipment being in working condition
Correspondence manual switching button display lamp light；
4) air-conditioning system master control system detect at any time A group air-treatment unit, B group air-treatment unit, water circulating pump A,
Stand-by equipment is switched to working condition immediately when any equipment breaks down by the operating condition of water circulating pump B, and
Stop faulty equipment operation；Before troubleshooting, current device is not limited continuous service by setting runing time.
Alarm function, A group air-treatment unit, B group air-treatment unit, water circulating pump is arranged in air-conditioning system master control system
When any appliance in A or water circulating pump B breaks down, or when can not normally switch, by the prompt of pop-up on a display screen and
Alerting tone alerts simultaneously, and shows abort situation.
Compared with prior art, the beneficial effects of the invention are as follows：
1) realize that the capital equipment of converter station valve hall air-conditioning system periodically automatically switches, manual switching and when failure are cut automatically
It changes, the degree of automation greatly improves, and extends service life of equipment；
