Abstract
The invention relates to a transformer compensator which solves the problems of large power loss and short service life of a transformer due to no load in the prior art. The transformer compensator is characterized in that a plurality of taps with different electric capacities are arranged on a capacitor, wherein one end of each tap is led out through a public terminal, and the other end is led out through a plurality of terminals. The invention has favorable application effect in the actual production and achieves the requirements of testing data standards with time and labor saving; the compensator has very simple design, principle and structure, focus on actual effects, achieves design requirements in technical indexes, accords with actual requirements in functions, is light in weight, easy to carry and monitor, convenient for wiring and small in field occupying area, brings guarantees for safety production and has unique property on technical aspects. The transformer non-load test compensator develops an active role in a non-load test, ensures that the power supply selection of the no-load test is clearer and simplified, promotes the development of a non-load test technology, has high cost performance and is suitable for being popularized and generalized.
Description
Technical field
The present invention relates to a kind of transformer accessory, relate in particular to a kind of transformer compensator.
Background technology
Have active loss during the power transformer no-load test, this loss is exactly a no-load loss.Power supply need provide two parts energy during no-load test, and the active loss that one is supplied with tested transformer is the no-load loss of transformer; It two is that the reactive loss of ironcore choke is the magnetic field energy that coil produces in alternating electric field, and this also is the part that will compensate.No-load loss directly influences transformer useful life and economical operation, must control.
Summary of the invention
The problem that the present invention is directed to above-mentioned existence of the prior art provides a kind of transformer compensator, solved in the prior art owing to unloadedly cause that kwh loss is big, transformer short problem in useful life.
Transformer compensator is characterized in that installing on the capacitor a plurality of taps of different capacitances, and an end of tap is drawn by a public terminal, and the other end is drawn by a plurality of terminals respectively.
Operation principle of the present invention:
From circuit diagram and vectogram as can be seen, capacitance current I
CWith inductance (magnetization) electric current I
OLDirection is opposite, as long as appropriate capacitor in parallel makes capacitance current equal inductive current, the reactive loss part in the time of just can compensating no-load test is left active loss (no-load loss) part, thereby has reduced the capacity of power supply.
Advantageous effect of the present invention:
The present invention's effect in actual production is good, reaches the requirement of time saving and energy saving test data standard, and the design of this kind compensation arrangement, principle, structure are all very simple, focus on actual effects; Technical indicator reaches designing requirement, and the realistic requirement of function is in light weight, carrying easily, and easy-to-connect, lack on-the-spot the occupation of land, and easily monitoring brings guarantee to safety in production; Has unique distinction at technical elements.The No-load Test of Transformer compensation arrangement is brought into play positive effect in no-load test, make the power supply of no-load test select more than you know, more simplification, has promoted the development of no-load test technology; The cost performance height.Be suitable for penetration and promotion.
