Description
Technical field:
The utility model relates to a kind of DC converter valve detection device, particularly relates to a kind of high voltage direct current converter valve cooling system on-line measuring device.
Background technology:
High voltage direct current converter valve operationally can produce amount of heat, its valve cooling system is cooled to high voltage direct current converter valve by the chilled water not stopping to circulate, once valve cooling system operation exception, high voltage direct current converter valve temperature will be caused sharply to rise, thus cause large area to damage, cause serious economic loss.
Current, high voltage direct current converter valve cooling system is configured with corresponding Control protection equipment, there is many-sided problem in it, one is that the setting of its control & protection strategy is based on the shop test before equipment installation and operation and simulation calculation, there are differences with the actual operating mode after equipment installation and operation, thus cause potential safety hazard; Two to be that definite value in above-mentioned strategy is arranged comparatively loose; insensitive to the change of parameter each in its protection domain; when detecting abnormal; to reach or close to trip value; be unfavorable for carrying out analysis and inspection to high voltage direct current converter valve cooling system running status; thus cannot find early and abatement apparatus hidden danger; three is do not have a kind of device that can carry out complete detection to high voltage direct current converter valve cooling device; pick-up unit in society is separate detection, between can not to carry out data upload defeated.
Utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, there is provided a kind of can carry out on-line checkingi to multiple parameters of high voltage direct current converter valve cooling device simultaneously, and there is the high voltage direct current converter valve cooling system on-line measuring device of instruction alarm function and expansion.
The technical solution of the utility model is: a kind of high voltage direct current converter valve cooling system on-line measuring device, comprise control device, router, pick-up unit, the interface of described router is connected with another router interface and pick-up unit, described control device is connected with pick-up unit by router, described router at least two.
Described control device comprises processor, display, alarm device, storer, power supply, filter amplification circuit, described display, alarm device, storer, filter amplification circuit are all connected with processor, described power supply is connected with processor and filter amplification circuit, and described alarm device comprises pilot lamp, hummer.
Described pick-up unit comprises single-chip microcomputer, detecting device, pilot lamp, storer, described single-chip microcomputer is connected with detecting device, pilot lamp, storer, described detecting device is arranged on high voltage direct current converter valve cooling device, and described detecting device comprises temperature detector, pressure detector, pump rotary speed detecting device, water leak detectors, voltage-level detector.
The beneficial effects of the utility model are:
1, the utility model can carry out on-line checkingi to multiple parameters of high voltage direct current converter valve cooling device simultaneously, also has instruction alarm and expansion and self-checking function, the operation of handled easily personnel, less labour intensity.
2, the utility model utilizes the advantage that the link of router is simple, easy to maintenance, be easy to expansion, and operating personnel can increase according to the situation at scene, and are provided with independent switch, reduce unnecessary waste of energy.
3, the utility model pick-up unit according to the time of setting detecting that information conveyance arrives control device, and can be shown monitoring information by display, detecting device is provided with pilot lamp, can shows the duty of detecting device.
4, the utility model is provided with pilot lamp and hummer, reminds operating personnel to note, by display, the relevant information of fault is shown, the operation of handled easily personnel simultaneously.
Accompanying drawing illustrates:
