The control system of a rain apparatus can realize adjustment of rainfall through a valve and the frequency converter control, the system adjustment is stable and reliable, and the anti-interference capability is strong.
Description
Technical field
The utility model relates to a kind of apparatus control system of drenching with rain, it is a kind of control system of in corona cage, simulating different rainfall amounts, this system regulates reliable and stable, antijamming capability is strong, easy to use directly perceived flexibly, the software interface close friend, for extra-high-voltage alternating current test base corona cage corona test provides good test condition, this system also can promote the corona cage that is used for other form structures and carry out corona test research.
Background technology
Along with the raising of voltage class of electric power system, the electromagnetic environment problem that the transmission line of electricity corona produces becomes increasingly conspicuous, and the corona effect problem has become the deciding factor of UHV transmission lead type selecting.To set up the research method input costs of several kilometers tests line segments and restringings big in order to study various physical dimension lead corona effects, cycle is long, adopt at present extensively and obtain data, and these data reductions are become the research technique of Value Data such as three-phase long transmission line from short test line segment and corona cage.Under the electric potential gradient of normal design, overhead transmission line can not produce a large amount of coronas under fine weather.The conductive line surfaces scrambling is the necessary condition that produces corona, for example under wet weather, water droplet attached to conductive line surfaces is the irregular place of conductive line surfaces, therefore and become main corona point, when the research lead is under the condition of drenching with rain corona characteristic, be necessary to design a kind of control system of simulating different rainfall amounts.Realize that with AC converter common employing control pressurer system is controlled in adjusting to pump capacity.Control pressurer system adopts AC frequency conversion speed regulator to regulate pump rotary speed, according to given water pressure value, realize the feedwater of constant pressure unsteady flow amount, this control mode is regulated flow by adjusting baffle plate or valve opening, thereby control rainfall amount, cause a large amount of waste of energy, and reduce the serviceable life of valve.
Therefore, be necessary to research and develop a kind of transformation power and be controlled to be flow control, promptly adopt AC converter to regulate pump rotary speed,, realize the control system of drenching with rain of the level and smooth electrodeless regulative mode of delivery rate, to satisfy the experimental study needs according to the given flow value.
Summary of the invention
The purpose of this utility model is: be controlled to be flow control by researching and developing a kind of transformation power, promptly adopt AC converter to regulate pump rotary speed, according to the given flow value, realize the control system of drenching with rain of the level and smooth electrodeless regulative mode of delivery rate, the mode that replaces tradition to regulate flow by the aperture of controllable register or valve not only can be saved a large amount of electric energy, and can improve valve serviceable life, reduce system noise simultaneously, improve the reliability of system.
The technical solution adopted in the utility model is: a kind of apparatus control system of drenching with rain, be used to control the amount of the drenching with rain size of corona cage, described control system comprises distant place switch board and variable frequency control cabinet, it is characterized in that, be provided with flowmeter between filtrator and the ball valve, actual by cmf record by the flow size, flowmeter is connected with distant place switch board, flow signal is sent to distant place switch board, distant place switch board compares actual flow and user's setting value, and start the variable frequency control cabinet and carry out inner PID and regulate, realize that closed loop regulates continuously.
The beneficial effects of the utility model are: this apparatus control system of drenching with rain is realized the simulation of corona cage light rain, moderate rain and heavy rain, rainfall can be adjusted by valve and Frequency Converter Control, system regulates reliable and stable, antijamming capability is strong, easy to use directly perceived flexibly, the software interface close friend is for extra-high-voltage alternating current test base corona test provides good test condition.
Description of drawings
Fig. 1 is the structural representation of the apparatus control system of drenching with rain of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Symbol description among Fig. 1: 1-cistern, 2-high pressure diving pump, 3-non-return valve, 4-filtrator, 5-flowmeter, the 6-draining valve, 7-ball valve, 8-corona cage, the 9-shower nozzle of drenching with rain, 10-split conductor, 11-valve one, 12-valve two, 13-variable frequency control cabinet, 14-distant place switch board.
The utility model provides a cover corona cage apparatus control system of drenching with rain, its automatic operation mode principle is according to the required rainfall amount size of test, switch board 14 is provided with by system software in the distance, start variable frequency control cabinet 13 immediately, cistern 1 inner high voltage submersible pump 2 is started working, current are through non-return valve 3, and through being sent to the front end of ball valve 7 after filter 4 filtrations, folding condition by adjusting valve 1 and valve 2 12 (totally three kinds: open by valve one, valve two is opened, and valve one, two all open) current are delivered to the shower nozzle 9 of drenching with rain of corona cage 8 tops, the simulation precipitation that satisfies the test demand is sprayed to split conductor 10, after feeding back to distant place switch board 14 according to flowmeter 5 reality by flow signal, compare with set-point, carry out inner PID by variable frequency control cabinet 13 and regulate, follow the trail of set-point automatically, the realization closed loop is regulated continuously.
This system also can be set to power frequency, manual mode, and by switch board 14 operation board upper knobs in a distant place are beaten to " power frequency pattern ", it is set to the power frequency pattern; By switch board 14 operation board upper knobs in a distant place are beaten to " manual mode ", will become manual mode.If rainfall need not to adjust, the power frequency pattern is an optimum working mode, and this moment, system was the most energy-conservation, also stable.Requiring at rainfall is not under the very accurate situation, needs the observation according to the amount of drenching with rain, and the optional test condition can adopt manual mode, adjusts console panel panel knob and changes the rainfall size.
If the rainfall size is clearly specified in testing requirements, then adopt automatic mode, be provided with by system software, adopt the PID closed-loop control to reach testing requirements rainfall environment rapidly.When adopting automatic mode, the startup of frequency converter and stop signal come from the host computer computer, by computer monitor software set rainfall, frequency converter carries out inner PID to be regulated, compare by flowmeter feedback signal and set-point, follow the trail of set-point automatically, the realization closed loop is regulated continuously.
This apparatus control system of drenching with rain is realized the simulation of corona cage light rain, moderate rain and heavy rain, rainfall can be adjusted by valve and Frequency Converter Control, system regulates reliable and stable, antijamming capability is strong, easy to use directly perceived flexibly, the software interface close friend is for extra-high-voltage alternating current test base corona test provides good test condition.
