Description
Technical field
The utility model belongs to the vacuum separation technical field, is specifically related to a kind of efficient transformer vacuum suction unit.
Background technique
Before high-power transformer puts into operation,, in order to ensure its insulating property, need to use the vacuum suction unit to vacuumize it before oiling, make moisture content in transformer, gas content reach safety standard requirements.In prior art, transformer comprises bleeding point, extraction valve, Roots blower pump, vacuum solenoid and the vacuum pump that connects successively by pipeline with the vacuum suction unit, and wherein the extraction valve pipeline is attached with vacuum transducer.There is following deficiency in this vacuum suction unit:
1, the vacuum suction unit is in vacuum, and part oily vapours, the water vapour of its extraction can attach to the vacuum transducer surface, cause Vacuum testing inaccurate, can damage vacuum transducer when serious.
2, the vacuum suction unit is in vacuum, and the oily vapours of its extraction, water vapour directly advance vacuum pump, sneaks in vacuum pump lubricant oil, pollutes vacuum pump lubricant oil, needs frequently more lubricant oil.
3, the vacuum suction unit is in vacuum, and the oily vapours of its generation, by vacuum pump, directly is discharged in atmosphere, to environment.
4, vacuum pump, Roots blower pump etc. all need manual start and stop, there is no the automatic control system, and without corresponding emergency alarm warning arresting gear.
Summary of the invention
For above shortcomings in prior art, the utility model provides a kind of transformer vacuum suction unit of efficient, long service life.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is as follows:
A kind of transformer vacuum suction unit, comprise bleeding point, extraction valve, Roots blower pump, vacuum solenoid, the vacuum pump that connects successively and control the automatic control electric device cabinet that each relevant device signal transmits, described extraction valve output terminal also is connected with vacuum transducer, be provided with air filter between described extraction valve and vacuum transducer, be provided with the air inlet condenser between described Roots blower pump and vacuum solenoid, in air inlet condenser lower end, be connected with the first oil trap.
Adopt the transformer vacuum suction unit of technique scheme, by between described extraction valve and vacuum transducer, air filter being set, making gas that vacuum transducer detects is clean gas after air filter filters, guarantee that degree of vacuum that vacuum transducer is surveyed is accurate, also avoid damaging simultaneously vacuum transducer; Before oily vapours, water vapour enter vacuum pump, become after liquid to be deposited in the first gathering room by the air inlet condenser condenses and store etc. pendingly, guarantee to enter vacuum pump without oily vapours, water vapour, vacuum pump is caused damage.
Furthermore, described vacuum pump output terminal also is provided with out gas condenser, goes out the gas condenser lower end and is connected with the second oil trap.While vacuumizing, the oily vapours that vacuum pump the produces condenser condenses of being given vent to anger becomes after liquid to be deposited in the second gathering room and stores etc. pendingly, guarantees to enter in atmosphere without oily vapours, causes environmental pollution.
Furthermore, described the first gathering room and the second gathering room are equipped with the warning device of being furnished with liquid-level switch and with liquid-level switch, coordinating.Collect fluid when the first gathering room and the second gathering room like this and reach when height is set, can autostop and by warning device, report to the police.
Description of drawings
Fig. 1 is that the utility model is faced structural representation;
Fig. 2 is the utility model side-looking structural representation.
Embodiment
, in order to make those skilled in the art understand better the utility model, below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated.
As depicted in figs. 1 and 2, a kind of transformer vacuum suction unit, comprise bleeding point 1, extraction valve 2, Roots blower pump 6, vacuum solenoid 8, the vacuum pump 9 that connects successively and control the automatic control electric device cabinet 7 that each relevant device signal transmits, described extraction valve 2 output terminals are connected with vacuum transducer 3, be provided with air filter 4 between extraction valve 2 and vacuum transducer 3, be provided with air inlet condenser 5 between described Roots blower pump 6 and vacuum solenoid 8, in air inlet condenser 5 lower ends, be connected with the first oil trap 10; Described vacuum pump 9 output terminals are provided with out gas condenser 12, go out gas condenser 12 lower ends and are connected with the second oil trap 11; Described the first gathering room 10 and the second gathering room 11 are equipped with the warning device of being furnished with liquid-level switch and with liquid-level switch, coordinating; collect fluid when the first gathering room 10 and the second gathering room 11 and reach when height is set, can autostop and by warning device, report to the police.
Under brief description, this transformer is with the working method of vacuum suction unit: in transformer, gas is by bleeding point 1 → extraction valve 2 → Roots blower pump 6 → air inlet condenser 5 → vacuum solenoid 8 → vacuum pump 9 → go out gas condenser 13, and gas is discharged in atmosphere finally.While at first setting Roots blower pump 6 startup degree of vacuum and transformer requirement degree of vacuum, then start vacuum solenoid 8 and vacuum pump 9, when vacuum pump 9 is extracted into Roots blower pump 6 startup degree of vacuum with transformer, Roots blower pump 6 starts automatically, when vacuum in transformer reaches when transformer requirement degree of vacuum is set, Roots blower pump 6 is out of service and send acousto-optic cue user, so that the user stops unit.
It is clean gas after air filter 4 filters that described air filter 4 makes vacuum transducer 3 gas that detects, and guarantees that vacuum transducer 3 degree of vacuum of surveying is accurate, and the while also avoids damaging vacuum transducer 3; While vacuumizing, air inlet condenser 5 can be deposited to the first gathering room 10 with after entering the front oily vapours of vacuum pump 9 and water vapor condensation becoming liquid, avoid oily vapours and water vapour to enter vacuum pump 9, vacuum pump 9 is caused damage, going out 12 of gas condensers is to be deposited in the second gathering room 11 after the oily vapours that vacuum pump 9 produces is condensed into liquid, guarantee to enter in atmosphere without oily vapours, cause environmental pollution.
The utility model use is simple, safe and reliable, pumping speed is fast, exhaust capacity is large, operating cost is low, each component capabilities is reliable and stable, adopts the condensation technology of giving vent to anger, and can reach the purpose of environmental protection and energy saving.
Above a kind of transformer that the utility model is provided is described in detail with the vacuum suction unit.The explanation of specific embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
