Description
Technical field
This utility model relates to overhauling special-purpose machines and tools, is specially a kind of portable transformer charged oil compensator.
Background technology
Oil-filled transformer built-in electrical insulation oil has the dielectric strength more much higher than air, has good cooling simultaneously and makees
With, insulant can be played maintenance, antisepsis, therefore insulating oil is extremely important for transformator.Real at equipment
In the O&M of border, a lot of situations all can cause transformer oil level too low, such as: the serious leakage of oil of transformator or long-term leakage of oil；Maintenance people
Member because of job demand (such as drawing oil sample), non-repairing after repeatedly draining the oil；Temperature is too low and conservator oil reserve is not enough, or conservator design is held
Long-pending little can not meet service requirement etc..The too low one side of transformer oil level can make light gas protecting action, during serious oil starvation, transformation
In atmosphere, there is lead-in wire electric discharge and dielectric breakdown accident in easy humidified insulation to device inner-core coil exposed.On the other hand meeting
Affecting on-load heat radiation, cause transformator running temperature to raise, if long-play is under limiting temperature, winding insulation is serious
Aging, and accelerate the deterioration of insulating oil, thus affect its service life.Therefore the oil condition of insulating oil directly influences oil immersion
The safe and stable operation of formula transformator.When transformator exist oil level too low and cannot have a power failure carry out traditional approach mend oil condition
Under, it is necessary to carry out live line oil make-up, although repairing amount is little, but still needs to use large-scale oil filter to carry out live line oil make-up, large-scale filter
Oil machine is primarily directed to the situation of power failure oil processing so self design discharge is relatively big, and drains the oil from the conservator note that caliber is less
When pipe carries out live line oil make-up, it is excessive to conservator internal impact, and oiling process easily entrains gas, thus causes Buchholz relay
Action, makes transformator be in an irregular operation state, on the other hand bulky due to large-scale oil filter, needs transport vehicle
Carrying, takes at the scene and carves the safe distance noted between charging equipment, require higher to Ground arrangement, be not therefore
Preferably repairing mode.For solving the problems referred to above, design portable transformer charged oil compensator, safe and convenient is entered
Line transformer live line oil make-up is significant.
Summary of the invention

The live line oil make-up unit that one is located in traverser, described live line oil make-up unit includes imported valve, and imported valve is through thick
Filter connects with the gear pump switched without oil guard, and gear pump outlet connects with high temperature protection switch and temp control switch
Heater, heater outlet connects with the filter of oil gauge, and filter outlet connects a check valve, one-way valved outlet
Connecting and have effusion meter, effusion meter connects special repairing pipe after outlet valve, and the end of special repairing pipe is provided with special repairing
Pipe end metal joint；Special repairing pipe end metal joint is the conservator Oil-filling and drainage valve flange-interface of standard, this splice port
Place uses pressure valve structure.
Described live line oil make-up unit also includes central console, gathers each parts switch and protection device in central console.
It is possible to prevent idle abrasion gear pump with the gear pump switched without oil guard；In the case of ambient temperature is too low right
When transformer oil heats, heater has overtemperature protection and temp regulating function；Can be by observing oil pressure instruction regulation tooth
Wheel pump power regulates repairing speed, and check valve can prevent transformer oil from refluxing, and the effusion meter that one-way valved outlet connects is used for remembering
Record repairing amount, special repairing pipe end metal joint is the conservator Oil-filling and drainage valve flange-interface of standard, uses pressure valve structure to set
Meter, is closed mode when device is not opened, and when oil pressure reaches certain value, pressure valve can be opened, and prevents air from entering oil pipe.
Device is furnished with central console, gathers each parts switch and protection device, it is simple to human users.
This utility model is portable transformer charged oil compensator, solves and lacks at present and can carry out charged to transformator
The problem of the small machine of repairing, it is easy and simple to handle, small volume, be easy to carrying, significantly reduce the difficulty of this type of work, carry
Effectively prevent from gas from entering oil circuit while high repairing efficiency to ensure safe and reliable to carry out repairing work, it is ensured that transformator is stable
Running, this device is simultaneously suitable for high-voltage shunt reactor is carried out live line oil make-up work.
