Abstract
The utility model provides a detection apparatus for reactor iron core short circuit ring, includes by mains operated's voltage regulator and power analyzer, connects on the voltage regulator and the interim winding of coiling on the reactor iron core that awaits measuring, the power analyzer connect in the both ends of interim winding. The utility model discloses to manual work investigation detect not enough, through electric device, utilize the basic principle of circuit and magnetic circuit, adoption 220V operating voltage can detect out whether have the short circuit ring between iron core return yoke and the splint. Easy operation, the effect is showing, alleviates working strength, improves detection efficiency, has guaranteed product quality, has shortened production cycle.
Description
Technical field
This utility model is related to the intimate detection field of reactor and in particular to a kind of detection of core of reactor short-circuited conducting sleeve fills
Put.
Background technology
With the continuous construction of extra-high voltage grid, demand in electrical network for the shunt reactor is increasing.Such reactor
In production process, when iron core return yoke and clamping plate step up, there may be short-circuited conducting sleeve between the two, easily cause during operation and be lost
Greatly, it is unfavorable for continually and steadily running.How simply and efficiently to detect that core of reactor whether there is short-circuited conducting sleeve and seems very heavy
Will.Traditional detection passes through whether artificial investigation return yoke constitutes loop it is desirable to testing staff is patient and painstaking with clamping plate, and workload
Greatly, check not comprehensive, be easily missed at virtual connection, there is hidden danger.
Content of the invention
For the problems referred to above, the utility model proposes a kind of detection means of core of reactor short-circuited conducting sleeve.
For solving the above problems, the technical scheme that this utility model is taken is：A kind of detection of core of reactor short-circuited conducting sleeve
Device, including the pressure regulator powered by power supply and power analyzer, is connected on pressure regulator and is wound in core of reactor to be measured
On interim winding, be equivalent to the Exciting Windings for Transverse Differential Protection in transformator, described power analyzer is connected to the two ends of interim winding.
On the return yoke of core of reactor, pressure regulator and power analyzer adopt 220V power supply to described interim winding technique
Power supply.Using pressure regulator, running voltage is adjusted it is ensured that powers is safe and reliable, power analyzer collection voltages, electric current
And power data, it is analyzed judging.
This utility model is directed to the deficiency of artificial investigation detection, by electric device, substantially former using circuit and magnetic circuit
Reason, be can detect that using 220V running voltage and whether there is short-circuited conducting sleeve between iron core return yoke and clamping plate.Simple to operate, effect shows
Write, mitigate working strength, improve detection efficiency it is ensured that product quality, shorten the production cycle.
Brief description
Fig. 1 is structural representation of the present utility model.
Wherein, 1, power supply, 2, pressure regulator, 3, power analyzer；4th, core of reactor, 5, interim winding.
Specific embodiment
As described in Figure, a kind of detection means of core of reactor short-circuited conducting sleeve, including the pressure regulator 2 powered by power supply 1 and work(
Rate analyser 3, it is connected on pressure regulator 2 and is wound in the interim winding 5 on core of reactor 4 to be measured, and interim winding 5 coiling
On the return yoke of core of reactor 4, power analyzer 3 is connected to the two ends of interim winding 5, and pressure regulator 2 and power analyzer 3 are adopted
Powered with 220V power supply.
By current-carrying capacity, the interim winding 5 for 50A is wound on the return yoke of core of reactor 4 first, and the number of turn is about 20 circles.
Then boosted it is ensured that output voltage has controllability by pressure regulator 2, by shown on readout power analyser 3
Voltage, electric current and power data, are analyzed judging with the presence or absence of short-circuited conducting sleeve to iron core 4.
When iron core 4 is normal, this device is equivalent to exciting current such as No-load Test of Transformer, electric current, for setting up master
Magnetic flux, loss is equivalent to open circuit loss, i.e. iron core iron loss, and numerical value is little；When there is short-circuited conducting sleeve in iron core 4, this device is as become
Depressor load test, electric current is equivalent to rated current, and loss is equivalent to load loss, i.e. winding copper loss, and numerical value is big, numerical values recited
Determined by the capacity of the voltage applying and transformator.
