Therefore, a control motor can be started and stopped outside the casing directly, which improves the adaptability to the environment, and moreover, the 12V low-voltage power supply is adopted, so that the safety performance can be effectively improved, and the trouble that the control cabinet is required to be opened during the starting-up every time can also be avoided.
Description
Technical field
The utility model relates to the Based Intelligent Control of oil field oil production equipment, specifically the oil pumping machine control cabinet safety switching apparatus.
Background technology
As everyone knows, the operational environment of oil-field oil pumper motor controlling cabinet is more special, all will be operated in field, work under bad environment, sunlight exposure, wind and weather throughout the year.If adopt regular tap directly to start, must open the door of control cubicle earlier, so staff's safety having been brought must hidden danger, does not also cause the understanding that people are enough at present.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of oil pumping machine control cabinet safety switching apparatus is provided, and controls industrial forceful electric power by being arranged on the outer low-voltage safety voltage of control cubicle, has increased processing safety greatly.
The technical scheme in the invention for solving the technical problem is: this kind oil pumping machine control cabinet safety switching apparatus, comprise control cubicle and main circuit, it is characterized in that, also comprise a starting or stopping control circuit, described starting or stopping control circuit is arranged in the independently cavity of control cubicle, the touch-switch of starting or stopping control circuit is arranged on control cubicle cabinet outside, the relay control termination main circuit of starting or stopping control circuit; The power supply of starting or stopping control circuit is for providing the DC power supply of safe voltage.
In the described starting or stopping control circuit, the output Q of d type flip flop connects positive pole behind a resistance R 1 and green LED D1, and the Q end is also connected on the base stage of triode Q1 simultaneously; The inverse output terminal Q of trigger connects positive pole behind a resistance R 2 and red light emitting diodes D2; The trigger impulse input CLK of described d type flip flop and the equal ground connection of level input D; Reset terminal R stops touch-switch S2 through one and is connected to positive pole, stops touch-switch S2 two ends and is parallel with capacitor C 3, simultaneously reset terminal R ground connection behind a protective resistance R4; Set end S connects positive pole behind a startup touch-switch S1, the end of set simultaneously S is ground connection behind a protective resistance R3 also; The collector electrode of triode Q1 connects positive pole after through a relay J, a described relay J voltage stabilizing didoe D3 in parallel; The grounded emitter of triode Q1; Between positive pole and earth connection, connect capacitor C 1 and C2.
The power supply of described starting or stopping control circuit is the DC power supply of 12V voltage.
The beneficial effects of the utility model are:
Adopt the starting or stopping control circuit of low voltage control, touch-switch is contained in control cubicle cabinet outside.Start like this/can directly carry out when stopping to control motor, the adaptability of environment is improved, and what adopt is the 12V low-tension supply, can effectively improve security performance, can also save the trouble that each start all needs to open control cubicle in the cabinet outside.
This oil pumping machine control cabinet safety switching apparatus is simple in structure, can reliable and stable work, can satisfy the job requirement of oil pumper.
Description of drawings
Fig. 1 is starting or stopping control circuit figure.
Among the figure: C1～C3 electric capacity, D1～D3 diode, R1～R4 resistance, Q1 triode, S1～S2 touch-switch, J relay, M main circuit.
Embodiment
As shown in Figure 1, this kind oil pumping machine control cabinet safety switching apparatus comprises control cubicle and control main line, also comprise starting or stopping control circuit, described starting or stopping control circuit is arranged in the independently cavity of control cubicle, the relay control termination main circuit of start-up control circuit, the start-up control circuit adopts the power supply of 12V low-voltage dc power supply.
Described starting or stopping control circuit is a center deployment with d type flip flop 4013, and its operation principle is to utilize the resetting of d type flip flop, switch that asserts signal is controlled main circuit.The output Q of d type flip flop connects positive pole behind a resistance R 1 and green LED D1, the Q end is also connected on the base stage of triode Q1 simultaneously; The inverse output terminal Q of trigger connects positive pole behind a resistance R 2 and red light emitting diodes D2; The trigger impulse input CLK of described d type flip flop and the equal ground connection of level input D; Reset terminal R stops touch-switch S2 through one and is connected to positive pole, stop touch-switch S2 two ends and be parallel with capacitor C 3, the effect of capacitor C 3 is to make the resetting time of d type flip flop greater than setting time, to reach the purpose that the trigger that powers at first enters reset mode at every turn, the back d type flip flop Q that can effectively prevent from like this to power on holds the stochastic regime that may occur, simultaneously reset terminal R ground connection behind a protective resistance R4; Set end S connects positive pole behind a startup touch-switch S1, the end of set simultaneously S is ground connection behind a protective resistance R3 also.The collector electrode of triode Q1 connects positive pole after through a relay J, a described relay J voltage stabilizing didoe D3 in parallel, and protection relay J's is stable; The grounded emitter of triode Q1.The signal of the output Q of described d type flip flop by control triode Q1 by and conducting drive the closing and closing of K of relay J, thereby the Push And Release of control main circuit M.For reducing external interference, between positive pole and earth connection, connect capacitor C 1 and C2, can also play the effect of isolating current potential.
Its course of work is that under the normality, trigger is in running order, Q is a high level, and green LED D1 lights, and the base stage of triode Q1 is a high level simultaneously, triode Q1 conducting, the K adhesive of relay J under the effect of electric current, main circuit M is in running order.Press S2, d type flip flop is reset, and output Q is a low level, and green LED D1 extinguishes, the Q end is high level, and triode Q1 ends, and the K of relay J disconnects, red light emitting diodes D2 lights, and expression main circuit M quits work, and unclamps S2 and does not influence the trigger reset state.Press S1, d type flip flop is set, and green LED D1 lights, red light emitting diodes D2 extinguishes, and Q is a high level, triode Q1 conducting, the K adhesive of relay J under the effect of electric current, main circuit M starts working simultaneously, unclamps S1 and does not influence trigger SM set mode.
According to the foregoing description, for other embodiment, persons skilled in the art can realize easily.
