Embodiment

[0011] Transformer compensator, as shown in the figure, 10 taps of 10 high-voltage capacitors are installed on the capacitor, and the power frequency AC withstand voltage is 15kV. One end of the tap is connected to a common nylon terminal C0, and the other end is respectively Lead out through 10 nylon terminals. The capacitor is installed in a sealed metal box 3. The inside of the metal box 3 is insulated with capacitor oil and capacitor paper. The outer surface of the sealed box 3 is provided with a handling handle 2.

[0012] Technical index of the present invention is as follows:

[0013] Working temperature: -20~50℃; capacitance error: C<1%; rated voltage: 15kV; rated capacity: 0.1~1.0④F(C0c1=0.1④F, C0c2=0.1④F, C0c3=0.1④F C0c4=0.1④F, C0c5=0.1④F, C0c6=0.1④F, C0c7=0.1④F, C0c8=0.1④F, C0c9=0.1④F, C0c10=0.1④F). The capacitor is installed in a sealed metal box, and the inside of the metal box is insulated with capacitor oil and capacitor paper. The terminals described are nylo...

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 [0001] The invention relates to a transformer accessory, in particular to a transformer compensator. Background technique [0002] The power transformer has active power loss during the no-load test, and this loss is the no-load loss. During the no-load test, the power supply needs to provide two parts of energy, one is the active loss of the transformer under test, that is, the no-load loss of the transformer; the other is the reactive loss of the core coil, that is, the magnetic field energy generated by the coil in the alternating electric field, which is also part to be compensated. The no-load loss directly affects the service life and economical operation of the transformer and must be controlled. Contents of the invention [0003] The present invention provides a transformer compensator aiming at the above existing problems in the prior art, which solves the problems in the prior art of large power loss and short service life of the transformer due...
