Description
One, technical field:
The utility model relates to the motor controlling cabinet of a kind of motor controlling cabinet, particularly a kind of oil-field oil pumper.
Two, background technology:
The electric equipment of control pumping-unit motor all adopts common starting switch cabinet at present, and 1. it is simple in structure.2. critical component is fragile, and useful life is short.3. performance is single, and automaticity is low, can only do the startup of motor and stops using.4. the unreasonable rain and snow poor performance of starting switch cabinet shell mechanism needs to wrap up rain and snow with Polypropylence Sheet at ordinary times.5. the cable end of turnover line separately causes cable end aging serious outside casing, and the aging back of insulating barrier metal wire contacts the human electric shock's accident etc. that takes place easily with casing.
Three, summary of the invention:
The purpose of this utility model is exactly the defective that exists at prior art, in order to prolong the useful life that starts cabinet, reduce labor strength, admission is in time also preserved the pumping-unit motor service data, rate when monitoring the oil recovery of rod-pumped well constantly, improve the water resistance that starts cabinet, prevent the generation of electric leakage accident, a kind of oil pumper measure control cabinet is provided.
Its technical scheme is: comprise casing and chamber door; instrument transformer, change over switch, A.C. contactor, motor protecter are installed in casing; it is characterized in that: kilowatt-hour meter, voltmeter, ammeter, supply socket and circuit breaker also are installed in casing; kilowatt-hour meter motor power end of incoming cables; voltmeter is connected in parallel on the electric power incoming line; ammeter is connected on the electric power incoming line, and supply socket is connected in parallel on the electric power incoming line, and circuit breaker is connected on the electric power incoming line.The naked terminal block of inlet wire copper-aluminium transition, the naked terminal block of outlet copper-aluminium transition also are installed in casing, power supply turnover line passes through the naked terminal block of inlet wire copper-aluminium transition, the naked terminal block of outlet copper-aluminium transition and is connected outward, magnetic-type door lock is housed between casing and the chamber door, the undergauge sebific duct is housed in the wire inlet-outlet of bottom half.
Control cubicle of the present utility model has solved the defective that existing pumping-unit motor control cubicle exists well, various parameters with digital record, storage and demonstration motor and electrical network, prolong the useful life of motor, the fail safe that improves control cubicle is from many aspects controlled simpler.
Four, description of drawings:
Accompanying drawing 1 is the structural representation of a kind of embodiment of the present utility model;
Accompanying drawing 2 is circuit theory diagrams.
Five, specific embodiment:
With reference to accompanying drawing 1, oil pumper measure control cabinet comprises 1, moulded case circuit breaker; 2, kilowatt-hour meter; 3, instrument transformer; 4, digital motor protector; 5, vacuum A.C. contactor; 6, voltmeter; 7, change over switch; 8, three-phase socket and plug; 9, the naked terminal block of inlet wire copper-aluminium transition; 10, the naked terminal block of outlet copper-aluminium transition; 11, the turnover line draw; 12, casing; 13, magnetic-type door lock.
With reference to accompanying drawing 2, the STP stop button; The ST start button; The KM A.C. contactor; DBH digital motor protection monitor; The M motor; H1 H2 H3 monitor through wires hole; FU1 FU2 FU3 insurance; Ammeter, voltmeter are connected respectively and are connected in parallel in the circuit and (do not draw among the figure).
Oil pumper measure control cabinet of the present utility model; it starts the cabinet following nine big characteristics of comparing with the oil pumper that generally uses at present: 1, digital electric motor protecting watch-dog has the operation maximum current value and the minimum current value that 1. can show triple line; and per 30 minutes records store the maximum current value and the minimum current value of B phase, preserve 30 days.Thoroughly solve the worker that recovers the oil in decades and enrolled the problem that the electric current data must be carried pincers type ammeter on the body, reduced their labour intensity.To the motor that operates steadily, time and changing value that the record stored current changes suddenly and rises or descend.2. write down time and changing value that stored voltage changes suddenly and rises or descend.3. can show year, month, day, hour, minute.4. can monitor time on electric motor starting date and record storage, preserve 30 days.5. can monitor motor and stop time on date and record storage, preserve 30 days.Hand push button when 6. at every turn making an inspection tour, record stores and presses the time on button date, preserves 30 days.7. pound sign or device number are set.8. the internal memory button cell is arranged, and the assurance data are not lost.9. by USB flash disk the data that store are exported.10. at the operation form of getting this equipment by computer.Use password, the data that store can all or part ofly be deleted.2. the actual power consumption that kilowatt-hour meter can write down every mouthful of oil well every day really is housed.Also measurable their power consumption when other unit's power supply for construction is so that reduce production cost.3. it has adopted the vacuum A.C. contactor thoroughly to solve the flimsy problem of medium-sized A.C. contactor, can make oil pumper start cabinet and increase the service life more than 2 years.4. voltmeter is housed, and whether the check system line voltage is normal simultaneously during each tours of inspection.Can check whether balance of three-phase line voltage when grid power blackout send electricity again, you cause motor to burn out can to prevent three characteristics of the middle term line Voltage unbalance.5. the naked terminal block of copper-aluminium transition is all adopted in the wiring of turnover line, adopts wiring to lean on the problem that often burns out before preventing.6. the space is big in the case, cable end directly enters in the case, four lines in the cable are transferred in case separately, directly receive on the naked terminal block of copper-aluminium transition, prevented that like this four lines in the cable from separately causing aging the electric leakage outside case, the bad cable that causes of cable end bag is irritated the generation that quick-fried cable fault takes place the water inlet that.7. cable directly enters in the case, has the draw that cable is tightened at the cable import and export, prevents that rainwater from causing short circuit to have an accident in cable flows to cartonning.8. each one of casing has adopted new-type waterproof construction, and thoroughly having solved electrical control cubicles is the problem that waterproof adopts the Polypropylence Sheet bag, and 9. chamber door adopts magnetic-type door lock, prevents that chamber door from closing the bad problem that is scraped off by strong wind.
