Description

The high-protection type oil pumping machine control cabinet

Technical field

The utility model relates to the oil pumping machine control cabinet of a kind of oil pumping machine control cabinet, particularly a kind of high-protection type.

Background technology

The oil pumping machine control cabinet long-term work wind, Exposure to Sunlight, drenches with rain in the open air, work under bad environment, and there is following defective in existing control cubicle: 1, the corrosion of control cubicle housing is very fast, and useful life is short; 2, whenever running into rain, snow weather, strong wind advances rain, snow wire hole by 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 electric shock or electricity easily take place hinder accident; 4, existing control cubicle easily comes in contact device main contact adhesion accident in start-up course.

Summary of the invention

The purpose of this utility model is the oil pumping machine control cabinet of a kind of high-protection type of design, eliminate the defective of existing control cubicle, prolong the useful life of control cubicle, the fail safe when the raising staff operates, reduce the generation of bad weather infringement accidents such as sleet, improve the oil well reliability of operation.

The purpose of this utility model is achieved in that and comprises housing; automatic air circuit breaker; intelligent motor protector; the vacuum A.C. contactor; enclosure interior is divided into a chamber by dividing plate; two chambers; one chamber is equipped with the operating grip of automatic air circuit breaker; the digital display screen of intelligent motor protector; start button; stop button; indicator light; two chambers are equipped with automatic air circuit breaker; the vacuum A.C. contactor; intelligent motor protector; load side outlet binding post; mains side inlet wire binding post; have the long cable section of ingoing line hole in two cavity bottom; the cable outlet hole, the operating grip of the automatic air circuit breaker of a chamber is connected with the automatic air circuit breaker of two chambers.

The beneficial effects of the utility model are: fitting operation part in the chamber, the forceful electric power element is installed in two chambers, dividing plate separates two chambers, two chambers can be separated with the external world, solved the defective that existing oil pumping machine control cabinet exists, have dustproof, the ability of anti-spraying, barrier propterty is good, effectively reduce the rate of failure that sleety weather causes, long service life operates in the chamber and finishes, handling safety coefficient height, guarantee staff's personal safety, can effectively improve the reliability and the processing safety of oil well electric power system, have remarkable economic efficiency benefit and social benefit.
