Description
The utility model relate to a kind of from deep-well the equipment of recover petroleum, especially a kind of power distribution equipment of pumping unit of well.
The power distribution equipment of existing producing well oil pumper adopts usually and is made up of in oil well mouth place separate connection motor and the distribution box of operating voltage 380V, and is that the oil pumper of a bite oil well is usually specially joined a supply transformer.Because oil pumper has bigger starting load, the factor that produces overload in the operation is more, thus the more powerful motor of apolegamy, thus cause load-rate of motor very low, the load factor of the transformer that especially is complementary is then lower.Be because the operating voltage of pumping unit of well is identical with the electric pressure of civilian electricity again, and controller switching equipment itself lack safeguard function, so the oil well that has often causes the stolen even damage of electric power and controller switching equipment, directly influences the normal oil producing operation of oil well.Particularly along with oil well density increases day by day, forming with the crude oil measurement station is the oil well group at center, make each oil well independently power distribution equipment can not adapt to the needs of development far away.
The purpose of the utility model provides a kind of novel pumping unit of well middle power distribution equipment of trooping, and improving oil pumper distribution system efficient, and makes it have thief-proof protection, centralized control functions; save the energy; reduce the loss, safeguard the normal oil producing operation of oil well, adapt to the needs of the development of recovering the oil.
For achieving the above object, the solution that the utility model is taked is: concentrate load on a door type frame mounting control protection distribution box of several pumping unit of well, be combined into mechanical oil recovery group of planes power distribution protection cabinet.According to power consumption corresponding supporting one or two transformers.Power distribution protection each control protection distribution box cashier's office in a shop connects matched separately pumping unit of well motor respectively; the operating voltage of motor adopts 1.14KV; terminal box on the motor adopts the protection terminal box that safe-guard door lock is housed, and is fitted with building-out capacitor in the terminal box.And in control protection distribution box, be equipped with the digital circuit formula integrated protector for electric motor that designs according to beam pumping unit pulsating load curve.Also installed the wireless remote control start stop apparatus of motor of oil extractor cashier's office in a shop at the composite type centralized power distribution.
Because having adopted, the utility model concentrate group to be linked as beam-pumping unit group power distribution protection cabinet the control protection distribution box of several pumping unit of well; one or two jumbo distribution transformer centralized power distributions of adapted replace the many station power distributions transformer that is scattered in each oil well field altogether; both improved the load factor of transformer; can significantly reduce the high voltage power transmission facility again; also make things convenient for oil recovery workman's maintenance and use, more helped developing the automatic management of oil well.The operating voltage of motor of oil extractor rises to 1.14KV; and be equipped with digital circuit formula comprehensive protection device; prosthetics electric capacity and with the protection terminal box of safe-guard door lock in also connection box for motor being designed to; the load factor of oil well distribution system improves greatly; and can prevent stealing effectively and damage distribution facility, safeguard the normal oil producing operation of oil pumper.At the equipped motor wireless remote control start stop apparatus of power distribution cabinet, control starting or stoping of oil pumper other just can the operation easily of oil well with remote control mobile phone.The utility model novel structure, reasonable in design, save the energy, improve usefulness, have thief-proof and function such as security protection, safe and convenient to use, be a kind of novel pumping unit of well centralized power distribution protective device.
