Test method of magnetically controlled reactor

Abstract

The invention provides a test method of a magnetically controlled reactor, which is characterized in that a serial circuit consisting of a capacitor bank and a reactor is connected with a magneticallycontrolled reactor in parallel and then is connected to a test transformer, a parallel resonant method is utilized, and capacitive reactive power of the capacitor bank is utilized to compensate the test transformer when the capacity of the test transformer is in short. When in low voltage, the output capacity of the magnetically controlled reactor is adjusted to ensure that the output capacity isslightly larger than the capacity of the compensated capacitor bank; and when in low voltage and small capacity, resonance points are evaded so as to protect the test equipment and avoid adverse results caused by resonance. Then voltage is boosted, the output capacity of the magnetically controlled reactor is adjusted to lead the output capacity of the test transformer to be minimum; and the voltage is continuously boosted, inductance is adjusted until the voltage and output power born by the magnetically controlled reactor meet test requirements. The test method ensures that the magneticallycontrolled reactor can satisfy design requirement when leaving the factory and run reliably and safely on site, thereby preventing the equipment from doing experiments on the site of a transformer substation and greatly saving manufacturing costs.

Description

technical field [0001] The invention belongs to a test method for a magnetron reactor (abbreviated as MCR) in a power system, which is mainly used for the test of the magnetron reactor after manufacturing, and belongs to the technical field of power system products. Background technique [0002] After the production and manufacture of the magnetron reactor is completed, routine testing and testing must be carried out. At present, the test of the magnetron reactor in the power system in the production plant cannot achieve the rated voltage and rated load state, that is, it cannot simulate the actual use conditions. The main reason is that the capacity of the magnetic control reactor is increasing day by day, and the test equipment of general enterprises has certain limitations. Taking the magnetic control reactor of model BKSF-12000 / 35 as an example, it is necessary to simulate the actual use conditions for it. , it is necessary to have a transformer with a voltage of 35kV an...

[0002] After the production and manufacture of the magnetron reactor is completed, routine testing and testing must be carried out. At present, the test of the magnetron reactor in the power system in the production plant cannot achieve the rated voltage and rated load state, that is, it cannot simulate the actual use conditions. The main reason is that the capacity of the magnetic control reactor is increasing day by day, and the test equipment of general enterprises has certain limitations. Taking the magnetic control reactor of model BKSF-12000 / 35 as an example, it is necessary to simulate the actual use conditions for it. , it is necessary to have a transformer with a voltage of 35kV and a capacity greater than 12000kVA, but for enterprises, this is basically impossible, so the test of rated voltage and rated load usually needs to be done at the substation site. If the magnetic control reactance There is a problem with the device, and it is very difficult to deal with it on site
