Description
Technical field
The utility model belongs to power distribution equipment technical field, and in particular to is exclusively used in the height of the 35KV electricity generation oil of oil drilling
Press cabinet.
Background technology
In industrial processes, particularly during oil field development, usual power resources are all diesel fuels, utilize bavin
Fry dried food ingredients electric power generation, then by being used after processing.With the development of oilfield applications and the development of power industry, power resources have
New paragon, electricity is provided after competent local power network power transformation for production, with instead of diesel fuel, this mode is just called electricity generation oil.
An important component of the drilling prospection as oil field development, it is Green drilling well, energy saving, cleaning, efficient
Production proposes requirements at the higher level as the fresh target of drilling well industry development to the energy saving and environmental-protecting performance of drilling machine.As environmental protection is anticipated
The raising of knowledge, the increase in short supply and diesel oil cost of petroleum resources, electricity are applied more and more extensive for the mode of oil.Net electric drill
Well is an important measure of drilling prospection industry energy-saving emission reduction, and one of the cost-effective increase benefit of drilling well industry is important
Behave.According to investigation, the power feasibility of drilling well height, economic benefit ten are provided instead of diesel-driven generator using the power supply of power grid
Divide considerable.
Oil changes the electric signal for needing some electric cabinets to provide power grid after electricity and handles, to control the output of electric power.Electric cabinet
Requirement of the working environment to temperature and humidity it is very high, the excessive aging that can accelerate electrical equipment of temperature, service life reduce;Temperature
Degree low humidity conference causes the moisture in air to liquefy on electrical equipment, reduces the insulation performance of element, and when energization easily occurs
Short circuit burns out electrical equipment.Particularly in hyperbaric environment, it is easy to short circuit phenomenon occurs.
Utility model content
The purpose of this utility model is:A kind of high-voltage board for the 35KV electricity generation oil for being exclusively used in oil drilling is aimed to provide, is carried
Its high temperature control and moisture-proof performance, make it also to ensure working environment even in rugged environment.
To realize above-mentioned technical purpose, the technical solution adopted in the utility model is as follows:Including high-voltage terminal cabinet, cabinet door,
Bottom plate and drier, the high-voltage terminal cabinet are hollow square box, and the square box one side is the cabinet for being capable of folding
Door, the bottom plate lower surface is fixedly connected on the madial wall of high-voltage terminal cabinet, if the upper surface of the bottom plate is fixedly connected with
Heavenly Stems and Earthly Branches fagging, the support plate are horizontally disposed with, and wire casing are equipped between the support plate, the wire casing is detachably in the upper table of bottom plate
On face, containing tank is horizontally fixed with the high-voltage terminal cabinet madial wall, the containing tank is groove, and the drier is positioned at Sheng
Put in groove.
The basic principle of this programme is that the support plate on bottom plate is used to fix various electric elements, enables electric elements
It is enough horizontally disposed, it can strengthen working effect the reason is that part electric elements are horizontally disposed with or extend its service life, such as one
Kind must be just horizontally disposed with using the triode that alcohol cools down can just maximize cooling effect.Wire casing between support plate uses
Common wire casing, the wire restraint in high-voltage terminal cabinet is fixed.The reason for setting bottom plate is the installation for avoiding electric elements
The side wall of high-voltage terminal cabinet is destroyed, extends its service life, while also allow for integrally taking out bottom plate into inspection.In addition, in 35kV
High pressure under, higher is required to the degree of drying inside high-voltage terminal cabinet, compared to slightly lower voltage, its electric elements inside by
To the influence bigger of environment, so placing drier inside high-voltage terminal cabinet, ensure the environmental drying inside high-voltage terminal cabinet,
Compare and other modes, the degree of drying higher of this programme, reliability are also stronger.Drier cannot be placed arbitrarily in electric cabinet again,
Horizontally disposed containing tank enables placement that drier stablizes wherein, and convenient unified management.At the same time can be by caloric value
Larger electrical equipment is arranged separately in a support plate, in order to which it radiates, with being directly installed on bottom plate or high pressure
Compared on outgoing line cabinet side wall, support plate also improves the area of installation, makes the ventilation of each electrical equipment and heat dissipation performance more preferable.
The beneficial effect of this programme is, is ensureing electricity generation oily device normal work at the same time, there is provided its heat dissipation performance and
Drying property, ensure that the working environment of electrical equipment is stablized, improves its work efficiency, extend the service life of device.
Further, slip pipe is further included, the slip pipe is cylindrical pipe, and the tube wall of the slip pipe is netted, slip pipe outer wall
Consistent with containing tank groove face profile, the slip pipe is placed in containing tank to be coordinated with containing tank, and the drier is uniformly placed on
In slip pipe.If drier is placed directly in containing tank, still may be touched when manually to being checked inside high-voltage terminal cabinet
It is also not convenient enough to drier, and when replacing drier, drier is put into slip pipe, this programme consolidates slip pipe
It is fixed more preferable, directly slip pipe is taken out when replacing drier and is replaced, it is convenient and efficient.
Further, the slip pipe is equipped with sliding block and sliding slot, axial lineal layout of the sliding slot along slip pipe, sliding slot connection
Slip pipe it is inside and outside, the sliding slot right end extends to slip pipe end, and left end has close to slip pipe end and with slip pipe end
1cm-2cm distances, the sliding block left end match with slip pipe inner surface contour, make sliding block with sliding slot clearance fit in the middle part of the sliding block
Be slidably arranged on sliding slot, the sliding block right end with it is bigger than middle part.In use, sliding block is first slided into a sliding slot left side by sliding slot right end
End, sliding block left end are located inside sliding slot;Drier is put into slip pipe again, it is necessary to when replacing drier, directly takes out slip pipe, it is sliding
Movable slider can take out all drier in slip pipe, solve inconvenience when taking out drier, meanwhile, sliding block blocks slip pipe
One end, if both ends all do not stop, be easy to allow drier to skid off in mobile slip pipe.
Further, air-conditioning is further included, the interior machine of the air-conditioning is fixed on above bottom plate, and the outer machine of air-conditioning is fixed on high extrusion
Above line cabinet, outside high-voltage terminal cabinet.The temperature in high-voltage terminal cabinet is adjusted using air-conditioning, further makes the work of electrical equipment
