Abstract
The utility model relates to power distribution equipment, and especially relates to a frequency energy-saving control cabinet, comprising a cabinet, a man-machine interaction device, a programmable logic controller, and a sensor. The frequency energy-saving control cabinet is characterized in that a front side plate of the cabinet is provided with an LCD, a power switch, indicator lamps, and control buttons. The programmable logic controller, a frequency converter, and the sensor are connected in sequence to form a closed loop circuit. The man-machine interaction device and the programmable logic controller are interconnected. The frequency energy-saving control cabinet saves energy with relatively high automation degree, prolongs service life of devices, and does not influence normal operation of other devices in a power grid.
Description
Technical field
The utility model relates to a kind of control electric installation, particularly a kind of energy-saving and frequency-variable switch board.
Background technology
Present low pressure transmission electric equipment control mode be generally direct startup or reduced-voltage starting, electric current is very large during startup, and electrical network is caused very large impact, not only the serviceable life of image documentation equipment, and easily produce harmonic wave and electric arc etc., affect the normal operation of other equipment in the electrical network.And automatic controlling level is lower, generally can't carry out to blower fan, water pump even load automatic control and the speed governing of flow, adds for a long time and operates at full capacity, thereby waste very much electric energy to a certain extent.
Summary of the invention
The utility model is intended to for the deficiency that exists in the background technology, and a kind of energy-saving and frequency-variable switch board that proposes.
Energy-saving and frequency-variable switch board of the present utility model, to be consisted of by casing, human-computer interaction device, programmable logic controller (PLC) and sensor, its feature is provided with LCDs, power switch, pilot lamp and control knob at the front side board of casing, programmable logic controller (PLC) in casing, frequency converter and sensor line connect the formation closed-loop path in turn, and the human-computer interaction device connects alternately with the programmable logic controller (PLC) circuit.
The utility model energy-saving and frequency-variable switch board is energy-conservation, and automaticity is higher, and has prolonged service life of equipment, does not affect the normal operation of other equipment in the electrical network.
Description of drawings
Fig. 1 is external structure synoptic diagram of the present utility model;
Fig. 2 is structure principle chart of the present utility model.
Embodiment
, be described further the utility model energy-saving and frequency-variable switch board below in conjunction with Fig. 1:
Energy-saving and frequency-variable switch board of the present utility model, to be consisted of by casing, human-computer interaction device, programmable logic controller (PLC) and sensor, front side board at casing 1 is provided with LCDs 2, power switch 3, pilot lamp 4 and control knob 5, programmable logic controller (PLC) 6 in casing 1, frequency converter 7 and sensor 8 circuits connect the formation closed-loop path in turn, and human-computer interaction device 9 connects alternately with programmable logic controller (PLC) 6 circuits.Wherein, LCDs links to each other by the communication interface of man-machine switching equipment with programmable logic controller (PLC) 6, and programmable logic controller (PLC) 6 is connected with frequency converter 7 again, forms frequency-changing control system.
The utility model programmable logic controller (PLC) is the core, as long as be used for collection and the output of logic control, signal, to the control of instruction, has reached the duty of user's requirement.The working environment at the touch-screen on the human-computer interaction device and display simulates scene, and the effect of monitoring production.
