Abstract

The utility model relates to a movable simple power transformer for petroleum drilling wells, which comprises a suspended insulator chain, a 66KV inlet wire frame, an isolating switch, a lightning arrester, a lightning arrester protector, a tank-type sulfur hexafluoride circuit breaker, a main transformer, a 6KV cable and sledges. The isolating switch and the lightning arrester are arranged on the two sledges in sequence. The lightning arrester protector is arranged at the periphery of the lightning arrester. The tank-type sulfur hexafluoride circuit breaker and the main transformer are respectively arranged on the sledges. The 66KV inlet wire frame is arranged on one side of the sledges loading the isolating switch and the lightning arrester. The suspended insulator chain is arranged on the 60KV inlet wire at the top of 66KV inlet wire frame. The 60KV inlet wire, the isolating switch, the lightning arrester, the circuit breaker and the main transformer are connected in sequence via steel-cored aluminum strands. The output terminal of the main transformer penetrates the steel pipe via the 6KV cable and then is connected with a 6KV power distribution box. The movable simple power transformer has the advantages of simple structure, easy installation and manufacture and convenient transportation, and overcomes the disadvantages of the immovable 66KV transformer station in the prior art; and is suitable for the short-term electricity supply for replacing oil in the oil-drilling machine and power supply and construction in small areas, with easy promotion and application.

Description

A kind of transportable simple transformation device

Technical field:

The utility model relate to a kind of be used for the field construction operation that can move particularly oil drilling for power distribution equipment, belong to for the distribution technique field.

Background technology:

In oilfield development process, need and produce needs according to the development plan design in the diverse location drilling well.Adopted in the past with the fuel oil to be that the machine dimensions drill of power not only expends fuel many, the cost height, and noise is big, maintenance workload is big, then there are shortcomings such as load-bearing capacity is low, radius of electricity supply is little, quality of power supply difference in the 6KV power supply of electric drilling machine employing at present, can not satisfy the construction production requirement under many situations, though and the 66/6KV transformation device that adopts usually belongs to the mature technique field, but this kind transformation device generally is fixed installation, inconvenience is moved, be not suitable for oily project short-term of rig electricity generation, zonule power mode, be difficult to satisfy on-the-spot actual needs.

The utility model content:

The purpose of this utility model is to provide the transportable simple transformation device of a kind of suitable rig electricity for oily short-term, zonule power mode.

The utility model is achieved in that

This kind transformation device by main transformer, pot type sulfur hexafluoride breaker, lightning arrester, isolating switch, 60KV inlet wire framework, suspension insulator string, steel pipe, lightning arrester block, 6KV cable and main transformer sledge, circuit breaker sledge and separate and the lightning arrester sledge is formed, the 66KV power supply is introduced by overhead transmission line or cable, 66KV equipment begins to be followed successively by isolating switch, lightning arrester, circuit breaker to main transformer by the inlet wire side, above-mentioned all devices is installed on the metal sled frame (sledge), be divided into different separate units, can make things convenient for handling, resettlement.During the work of this transformation device, the scene also need be equipped with auxiliary equipment such as low capacity direct current system, control and protective relaying device and communication system, supervisory control system, to guarantee the operate as normal of transformation device and normally carrying out of wellbore construction.

The utility model is simple in structure, is easy to install to make, and move easy to usely, can overcome the immovable shortcoming of traditional 66KV electric substation, is suitable for the rig electricity for oily short-term, the production of zonule power mode, work progress, is suitable for and applies.
