The power distribution cabinet mainly comprises a current transformer, a thermal-sensitive heat carrying electrical equipment, a three-phase alternating contactor, a three-phase breaker, a fuse, an intermediate relay, a PLC unit, a solid-state relay, a voltage transform unit, a current transform unit, a rotary switch, a stop button, a red indicating lamp, a pointer voltmeter, a temperature display unit, a pointer ammeter, a green indicating lamp, and a starting button, wherein the above-mentioned parts are connected mutually. 380-V three-phase alternating currents are used for supplying power for heating. The PLC unit controls an output unit to carry out intermittent power supply to switch a direct current device so as to carry out detection on a resistor, so that processing on data is carried out; and a temperature component is determined by a resistance value of a heating wire. According to the invention, the power distribution cabinet is widely applied to power distribution cabinet manufacturing by production manufacturer; problems that temperature measurement, display and control can not be carried out in a special environment and under a special working demand of normal detection can be solved.
Description
Technical field
The present invention relates to three high-power thermal control power distribution cabinet fields that add of oil well, be specially a kind of special power distribution cabinet.
Background technology
At present, steam injection is generally used in oilfield heating, and prescribe medicine such as lights at heating means; Operation is complicated; Contaminated environment, heat runs off serious, is difficult to produce a desired effect; Particularly can't realize the environment for use measured in complicated and conventional method, said method and existing power distribution cabinet can't satisfy the heating of oil well inside and the requirement of thermometric.
How a kind of green intelligence is provided; The high-quality special purpose power distribution cabinet of energy-conserving and environment-protective; Fill up domestic and international blank; The inventor lasts the several years and makes great efforts and seek, and has realized three high-power overlength heating cable of a kind of employing oil well, three high-power temperature control technology solutions that add thermal control power distribution cabinet composition of oil well.
The inventor is through a large amount of experiments and repeatedly research, adds the temperature control technology that the thermal control power distribution cabinet is formed by three of three high-power overlength heating cable of oil well and oil wells are high-power.Require down at the particular surroundings that can't realize conventional sense, particular job, realized the performance of temperature survey, demonstration, control.
According to this discovery, the inventor has obtained brand-new breakthrough according to principles such as the resistance value of thermo electric material and variation of temperature relations in temperature control technology, finally successfully develop three high-power thermal control power distribution cabinets that add of oil well.
Summary of the invention
The present invention makes adaptable across power distribution cabinet manufacturer, can solve in the particular surroundings that can't realize conventional sense, and particular job requires down, carries out blank or the like the shortcoming problem of temperature survey, demonstration, control.
Technical scheme of the present invention is:
This special power distribution cabinet is mainly by current transformer, hot irritated heat-carrying electrical equipment, three-phase ac contactor, three-phase breaker, fuse, auxiliary relay, PLC unit, solid-state relay, voltage fluff unit, electric current transducing unit, rotary switch, stop button, red led, pointer voltmeter, temperature display unit, pointer ammeter, green indicating lamp, start button; Interconnect; Through three-phase alternating current 380V power supply heating; PLC unit controls output unit intermittent power supply switches flow directing device resistance is detected; Data are handled; Confirm temperature through the heating wire resistance, form the high-power overlength heater of oil well three-phase power distribution cabinet.
Described power distribution cabinet is realized the function to temperature survey, demonstration, control without the temperature acquisition element.
Described power distribution cabinet is through alternating current-direct current switching way measuring resistance.
Described power distribution cabinet adopts three high-power overlength heating tubes of oil well.
The invention has the beneficial effects as follows:
1, special power distribution cabinet is safe and reliable.According to different temperatures, the accurate control of different application function power distribution cabinet precisely connects, and forms powerful condition of work, can effectively increase the high-power overlength heating tube of three of oil wells useful life, keeps the power distribution cabinet operation lastingly firmly.
2, special power distribution cabinet high life.Because it is output unit that this special power distribution cabinet has adopted the high-performance solid-state relay, avoid high-voltage contact machinery break-make, promptly safety improves useful life again.
3, special power distribution cabinet is workable.This special power distribution cabinet has human oriented design, is provided with display screen, in real time temperature is shown, and function is set, and can make control more accurate according to the different different parameters of needs input.
4, special power distribution cabinet energy-conserving and environment-protective.Because this special power distribution cabinet adopts the high-performance solid-state relay, break-make is adjusted with temperature automatically, has significantly reduced power consumption.This special power distribution cabinet adopts zero cross fired, has reduced the generation of harmonic wave, avoids the pollution to electrical network.
The present invention can be widely used in the manufacturing of three special power distribution cabinets of high-power overlength heating tube of oil well.
In a word, the present invention has filled up in the particular surroundings that can't realize conventional sense, and particular job requires down, and the blank of carrying out temperature survey, demonstration, control has characteristics such as safe and reliable, high life, workable, energy-conserving and environment-protective.
