Abstract

Provided is a static compensation type control cabinet of an oil-pumping machine. The interior of a control cabinet casing is divided into a first cavity, a second cavity and a third cavity by partition boards. An operation handle of an automatic air breaker, a power-factor meter, a start button, a stop button and an indicating lamp are arranged in the first cavity. An automatic air breaker, an alternating current contactor, a motor protector, a control transformer, a load lateral outlet wiring column and a power supply lateral inlet wiring column are arranged in the second cavity. An automatic air breaker, a grouping automatic air breaker and a compensating capacitor group are arranged in the third cavity. Input capacitance capacity is determined according to the power and the actual measured reactive data of a motor of the oil-pumping machine, and compensation capacitance is input simultaneously when the motor is started up, so that power factor of an oil well power supply system is increased, line loss rate is reduced, and economic benefit is remarkable. An operation part is arranged in the first cavity, strong electricity component chambers are arranged in the second cavity and the third cavity respectively, the three cavities are separated by the partition boards, and operation is finished in the first cavity, so that the static compensation type control cabinet has high operation safety.

Description

Static compensation formula oil pumping machine control cabinet

Technical field

The utility model relates to a kind of oil pumping machine control cabinet, particularly a kind of static compensation formula oil pumping machine control cabinet.

Background technology

There is following defective in oil pumping machine control cabinet in production run: 1, control cubicle does not have the reactive power compensation measure, and power factor is low, and line loss is big, and is not energy-conservation; 2, whenever running into rain, snow weather, strong wind advances rain, snow wire hole through crack between a door and its frame and cable and is blown in the control cubicle, causes short circuit accident; 3, control cubicle forceful electric power road part and operation part mix, and coefficient of safety was low when the staff operated, and are prone to generation electric shock or electricity and hinder accident.

Summary of the invention

The purpose of the utility model is a kind of static compensation formula oil pumping machine control cabinet of design; Improve the power factor of oil well electric power system, reduce line loss, the fail safe when the raising staff operates; Reduce the generation of bad weather infringement accidents such as sleet, improve the running quality of oil well.

The purpose of the utility model is achieved in that and comprises housing, automatic air circuit breaker, motor protector, A.C. contactor, compensation condenser; Enclosure interior is divided into a chamber, two chambers, three chambers by dividing plate; One chamber is equipped with operating grip, power factor meter, start button, stop button, the indicator light of automatic air circuit breaker; Two chambers are equipped with automatic air circuit breaker, A.C. contactor, motor protector, control transformer, load side outlet binding post, mains side inlet wire binding post; Three chambers are equipped with automatic air circuit breaker, grouping automatic air circuit breaker, capacitor group; One chamber, two chambers are enclosed construction; The capacitor group links to each other with the grouping automatic air circuit breaker, and the grouping automatic air circuit breaker links to each other with automatic air circuit breaker, and automatic air circuit breaker links to each other with load side outlet binding post.

The beneficial effect of the utility model is: automatic air circuit breaker, grouping automatic air circuit breaker and capacitor group are installed in the control cubicle; Capacity and the idle data of actual measurement according to the oil pumper auxiliary motor; Drop into the capacitor group of respective volume with the grouping air circuit; Under the situation that does not increase supplementary load loss, carry out reactive power compensation, improve the power factor of oil well electric power system; One chamber, two chambers are enclosed construction, and barrier propterty is good, effectively reduce the rate of failure that sleety weather causes; Fitting operation part in one chamber is installed as forceful electric power element chamber in two chambers and three chambers, and dividing plate separates three chambers; Operate in the chamber and accomplish; The handling safety coefficient is high, guarantees staff's personal safety, has remarkable economic efficiency and social benefit.
