Technical field
The utility model relates to a kind of centralized energy supply system, the control cabinet particularly in a kind of energy supplying system.
Background technique
In traditional power distribution control system, electric closet and self-control cabinet separate design, separate configuration.Owing to being separately design, Design for Automatic Control Engineering and electrical design thinking there are differences, and Products Compatibility is poor, reduce flexibility and the accuracy of system.Because electric closet and self-control cabinet are separate configuration, automatic control equipment is caused to arrange too concentrated, inadequate with the conjugation of electric closet; On the other hand, self-control cabinet is connected a large amount of signaling line of needs with electric closet, causes the reliability and stability of robot control system(RCS) to reduce, and increases cost of investment.
Model utility content
The purpose of this utility model is to provide a kind of Intelligent control cabinet for water pump of centralized energy supply system, by electric closet and control cabinet integrated design, can carry out intelligent control to the pump motor of centralized energy supply system.
The technological scheme that the utility model provides is:
A kind of Intelligent control cabinet for water pump of centralized energy supply system, comprise rack, cabinet front is provided with man-machine interface screen, intelligent electric meter, single-phase air circuit breaker, three-phase air circuit breaker, A.C. contactor, intelligent controller, frequency variator is provided with in rack, described intelligent controller controls the output of frequency variator for the data-signal that collecting sensor transmits, and regulates the operation of water pump; Be provided with upper mounting plate and lower installation board in described rack, upper mounting plate fixed three-phase air circuit breaker, lower installation board fixes A.C. contactor.
Intelligent controller in robot control system(RCS) combines with electrical distribution system by Intelligent control cabinet for water pump of the present utility model, a control cabinet can be regarded as an independently mini system, can control separately it, also can together with other control cabinets coordinated signals.In whole HVAC process system, there is multiple mini system to control simultaneously, both can accomplish to be independent of each other, also can accomplish the complementary operation between mini system.
Improve Security: by the combination of strong and weak electricity, built-in measurement circuit breaker and multifunction instrument, measurement and controlling functions can be provided.
Improve stability: owing to shortening wiring distance, optimization control cabinet layout, reduces the probability of line failure.And be convenient to maintenance repair and the maintenance of attendant.
Simple to operate: by man-machine interface screen on control cabinet, operator can every data of fetch equipment intuitively.Operation interface is short and sweet, is easy to left-hand seat.
Accompanying drawing explanation
Fig. 1 is structural representation one of the present utility model.
Fig. 2 is structural representation two of the present utility model.
Fig. 3 is control flow chart of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Shown in Fig. 1,2, a kind of Intelligent control cabinet for water pump of centralized energy supply system, comprise rack 10, rack 10 front is provided with man-machine interface screen 6, intelligent electric meter 1, single-phase air circuit breaker 2, three-phase air circuit breaker 3, A.C. contactor 4, intelligent controller 5, frequency variator 7 is provided with in rack 10, be provided with upper mounting plate 8 and lower installation board 9 in rack 10, upper mounting plate 8 fixed three-phase air circuit breaker 3, lower installation board 9 is fixed A.C. contactor 4.
The operation frequency that Intelligent control cabinet for water pump mainly supplies the temperature on water return pipeline according to being arranged on, pressure transducer regulates chilled water pump, to meet system cloud gray model requirement.
Intelligent controller in Intelligent control cabinet for water pump is responsible for the data-signal of collecting sensor transmission and is processed, and according to the data-signal collected, controls the output of frequency variator, thus regulates the operation of water pump.By the mutual communication of RS485 bus between each chilled water pump Intelligent control cabinet, and carry out communication with centralized control cabinet.Intelligent control cabinet is by the combination of strong and weak electricity, and built-in measurement circuit breaker and multifunction instrument, can provide measurement and controlling functions:
(1) remote monitoring can be carried out for circuit breaker;
(2) collection of circuit breaker information;
(3) breaker protection setting value display verification;
(4) circuit breaker tripping fault recording;
(5) circuit breaker operation maintenance information;
(6) the aging management of circuit breaker;
(7) circuit breaker failure early warning;
(8) security recovery instructs.
Operator can shield by the man-machine interface be arranged on cabinet setting and the reading of Intelligent control cabinet being carried out to parameter.Intelligent controller, for controlling the mode of operation of water pump, can carry out the setting of Three models to chilled water pump: power frequency pattern, fixed pattern, variable mode frequently; When needs water pump long-time stable works, water pump is set as the power frequency pattern with 50Hz frequency operation by intelligent controller, when needs water pump works under different operating mode, what water pump was set as that fixed frequency runs by intelligent controller determines frequency pattern, freely switch under different operating modes as required, when needs water pump adjusts operating mode in real time, water pump is set as the variable mode that frequency of okperation changes in real time by intelligent controller, when water pump works under variable mode, frequency controls according to system pressure difference change, and the pressure point measuring fluid pressure is located at pipeline bottom; Pressure difference is monitored by the pressure transducer be separately positioned on confession, water return pipeline, and pressure monitoring result is transferred to differential pressure controller, and the pressure transducer that same water system is installed is arranged on same absolute altitude; As shown in Figure 3, when going out, backwater pressure reduction is when being greater than setting value, reduces a wherein pump capacity, if water pump has reached its minimum discharge, then close this pump, carried out variable frequency adjustment to another water pump by frequency variator for control flow; When going out, backwater pressure reduction is when being less than setting value, increases a wherein pump capacity, if this water pump has reached its peak rate of flow, then transfer this pump to power frequency mode operation, started another water pump, and carried out variable frequency adjustment to it by frequency variator; Set temperature sensor in water pipe and return pipe simultaneously, control frequency is carried out by water temperature difference, temperature transducer adopts plug-in type water pipe temperature sensor, and transducer probe assembly is arranged in the main flow area of current, when confession, backwater temperature difference are greater than setting value, reduce a wherein pump capacity, if water pump has reached its minimum discharge by frequency variator, then close this pump, variable frequency adjustment is carried out to another water pump; When confession, backwater temperature difference are less than setting value, increase a wherein pump capacity by frequency variator, if this water pump has reached its peak rate of flow, then transfer this pump to power frequency mode operation, started another water pump, and variable frequency adjustment is carried out to it; When the pressure reduction of water pipe and return pipe and the temperature difference all meet setting require time, frequency variator maintains PID constant output.
