Abstract
A novel frequency-converting electric control system for a hoisting winch comprises a power cabinet, a frequency conversion cabinet, a brake resistance cabinet and an operation platform, wherein the power cabinet consists of a knife switch and a circuit breaker; the frequency conversion cabinet consists of a frequency converter and a brake unit; the brake resistance cabinet consists of a brake resistor; and the operation platform consists of a PLC, a brake handle, a master handle and a touch display screen. The electric control system is characterized in that the knife switch is connected with the circuit breaker and controls the output of a power supply at the same time; an output terminal of the circuit breaker is connected with an input terminal of the frequency converter; the frequency converter is connected with the brake unit and also connected with the brake resistor at the same time; an output terminal of the circuit breaker is connected with the PLC; the PLC is also connected with the frequency converter; an input terminal of the PLC is connected with the master handle and the touch display screen at the same time. The utility model has the functions of tracking and power-saving, soft start and stepless speed adjustment, and has the advantages of simple operation and high safety coefficient, thereby reducing energy consumption, improving safety performance and achieving the effect of the safety production.
Description
Technical field
The utility model relates to a kind of later-model lifting winch frequency conversion electrical control system in the control system zone of gig in the mining industry.
Background technology
At present, China's overwhelming majority mine hoist adopts traditional old-fashioned hoister control system, but the weak point of old-fashioned hoister control system is apparent, the driver is in the very trouble that operates, normal because of the former of complicated operation thereby cause meaningless personal casualty, and the energy consumption extra-high-speed all brings no small economic loss for country and individual.
Summary of the invention:
The purpose of the utility model frequency conversion electrical control is not enough and a kind of later-model safety performance height, lifting winch frequency conversion electrical control system easy and simple to handle are provided in order to solve appeal, to cut down the consumption of energy, reduces dangerously also preventing to cause casualties.
A kind of later-model lifting winch frequency conversion electrical control system of the utility model is by power cabinet, frequency conversion tank, braking resistor cubicle, operator's station four parts are formed, wherein power cabinet is made up of disconnecting link switch and circuit breaker, frequency conversion tank is made up of frequency converter and brake unit, braking resistor cubicle is made up of braking resistor, operator's station is by PLC, brake handle, the main handle that makes, touch display screen is formed, it is characterized in that frequency conversion tank is the speed control device of this system, frequency conversion tank cabinet door is provided with guidance panel, utilize it can carry out the setting of parameter to converter plant, each operating handle on the operator's station can conveniently be controlled the operation of gig, touch display screen is used for showing the running state of gig, the service condition of operational factor and various controlling parts, has monitoring function, it is characterized in that leading the lock switch is connected with circuit breaker, control the output of power supply simultaneously, the mouth of circuit breaker is connected with the input end of frequency converter, frequency converter is connected with brake unit and is connected with braking resistor again simultaneously, the mouth of circuit breaker is connected with PLC, PLC is connected with frequency converter again, and the input end of PLC connects main make handle and touch display screen simultaneously.
The utlity model has the tracking electricity-saving function, soft start and stepless time adjustment function, easy and simple to handle, the safety factor height, thus cut down the consumption of energy and improve safety performance, reach the effect of safety in production.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a schematic circuit of the present utility model
The specific embodiment:
According to a kind of later-model lifting winch frequency conversion electrical control system of the utility model shown in Figure 1 is by power cabinet, frequency conversion tank, braking resistor cubicle, operator's station four parts are formed, wherein power cabinet is made up of disconnecting link switch and circuit breaker, frequency conversion tank is made up of frequency converter and brake unit, braking resistor cubicle is made up of braking resistor, operator's station is by PLC, brake handle, the main handle that makes, touch display screen is formed, wherein leading the lock switch is connected with circuit breaker, control the output of power supply simultaneously, the mouth of circuit breaker is connected with the input end of frequency converter, frequency converter is connected with brake unit and is connected with braking resistor again simultaneously, the mouth of circuit breaker is connected with PLC, PLC is connected with frequency converter again, and the input end of PLC connects main make handle and touch display screen simultaneously.
Want during operational system earlier disconnecting link switch and circuit breaker to be closed, power supply is opened at random, all devices is given in power supply simultaneously, the main handle that makes of operation, by the main handle control PLC that makes, PLC sends signal to frequency converter then, running velocity by the electrical motor on the Frequency Converter Control winch, control the operation of winch with this, the too fast meeting of winch running velocity produces electric current automatically and turns back to frequency converter, and the voltage of frequency converter itself will increase, when frequency converter voltage surpasses 630V, braking resistor cubicle and brake unit will discharge the unnecessary voltage in the frequency converter, and the voltage control that makes frequency converter is in normal range, and winch normally moves.
