Problems solved by technology

[0002] With the construction and development of ultra-high voltage and ultra-high voltage power grids, for longer transmission lines, in order to limit power frequency and operating overvoltage, it is necessary to configure high-voltage shunt reactors on the lines, but conventional high-voltage shunt reactors cannot be adjusted. When the power is close to the natural power or transmits larger power, the ordinary parallel high-resistance cannot be adjusted and withdrawn, causing the system voltage to drop, affecting the safety and stability of the power grid and power quality, and limiting the transmission capacity of the line

Embodiment Construction

[0012] Accompanying drawing is embodiment of the present invention.

[0013] Below in conjunction with accompanying drawing, the content of the invention is further described:

[0014] refer to figure 1 As shown, the main body is composed of a transformer-type main reactor and a graded reactor. The primary coil A-X is directly connected to the network, and the secondary coil circuit a-x is connected in series with graded reactors XK1, XK2, and XK3. Each graded reactor is connected in parallel with Circuit breaker D and thyristor device TK are connected in series with isolating switch K, and its isolating switch K1 is connected between the circuit breaker D1 and the thyristor device near the end of the loop node a; the isolating switch is connected between the circuit breaker and the thyristor near the end of the loop node a1 between the devices; the isolating switch is connected between the circuit breaker and the thyristor device near the end of the loop node a2; that is, th...

Abstract

The invention relates to an alternating-current controllable paralleling reactor comprising a transformer type main reactor and a step reactor. Wherein, the first coil is the main coil which connects the network directly; the second coil is the control coil outside which a break and a thyristor controller are mounted; the third coil is the compensating coil outside which a filtering compensating unit is mounted; and the transformer type main reactor and the second side-connect step reactor are both mounted in a fuel tank to form the body of controllable reactor. The alternating step controllable single-phase paralleling reactor comprises the body with high resistance, the breaker, the thyristor controller and the central controller, and it has the functions and characters which common reactors do not have, including: simply adjusting, rapid response time, non-harmonic-wave, lower noise, lower vibration, high reliability, lower consumption, and it can separate the harmonic wave to reduce the effect to electrified wire netting. The invention can be used in the electrified wire netting of extra-high voltage and long-distance power transmission.

Description

technical field [0001] The invention relates to a reactor used on a power transmission line, and is particularly suitable for an AC step-controlled single-phase or three-phase shunt reactor device. Background technique [0002] With the construction and development of ultra-high voltage and ultra-high voltage power grids, for longer transmission lines, in order to limit power frequency and operating overvoltage, it is necessary to configure high-voltage shunt reactors on the lines, but conventional high-voltage shunt reactors cannot be adjusted. When the power is close to the natural power or transmits larger power, the ordinary parallel high-resistance cannot be adjusted and withdrawn, causing the system voltage to drop, affecting the safety and stability of the power grid and power quality, and limiting the transmission capacity of the line. Contents of the invention [0003] The purpose of the present invention is to provide a step-controllable shunt reactor with simple...
