Adopts dynamic compensation method, fundamentally solve the compensation system series resonance overvoltage and best compensation between conflicting issues. It is well known that the arc suppression coil without any benefits during normal operation of power grids, if then tune into a state of full compensation or close to full compensation, there will be a series resonance overvoltage by raising the neutral point voltage, power grid normal operation and all sorts of single-phase grounding fault may produce dangerous overvoltage. So when the normal operation of power grids, adjust the arc suppression coil makes the tracking grid of capacitive current change bad no, which is specified by the department of electric power "fixed arc suppression coil can't work in a state of full compensation or close to full compensation". Like domestic automatic compensation device are servo system, is in front of the grid has not yet occurred ground fault the arc suppression coil to adjust to a state of full compensation for ground fault occurs, it is to avoid excessive series resonance overvoltage and a damping on the arc suppression coil in series

Arc Suppression Coil

THXH series arc-suspension coil complet compensation installation can change inductive current compensation of the arc suspension coil by changing inductance L. Advantages: strong adaptability in electrical network, extremely short response time and automatic detection and identification of the running status of electrical network via computer-based controller. During normal operation of the electric network, it can real-time calculate the capacitive current of the power network to earth and the out-of-resonance of power compensation network. It can realize quick and rational compensation in case of single-phase earthing.

(1), using the technology of controllable silicon, the compensation current is 0 ~100% of rated current range of continuous stepless adjustment, realize large-scale precise compensation, but also to adapt to the different needs of the powerdistribution network in different development period.

(2), the use of short circuit impedance as the working resistance, the volt ampere characteristic in the range of 0 to 110%UN is maintained in excellent linearity,which can achieve precise compensation.

(3), the arc suppression coil with adjustable belongs to, do not need to be installed damping resistance, also won't appear a series resonant, it not only improves the reliability of the operation, but also simplifies the equipment.

(4) when a single-phase earth fault occurs in the arc suppression coil is the fastest 5ms output compensation current, thereby suppressing arc, prevent airionization caused by arc caused by phase to phase short circuit; at the same time, it can effectively eliminate the repeated single-phase grounding fault are separated by a short time.

(5), complete sets of equipment without transmission, a rotating mechanism, high reliability, low noise, simple operation and maintenance.

Q:Transmission system and distribution system: Distribution system is the power supply to the distribution load for the purpose of the general voltage level of not more than 10KV

Q:Transmission and transformation equipment: Because of the need to change the current in the process of transmission, so the current transfer is called power transmission.

Q:What is the transmission line, what is the power distribution equipment: Transmission lines generally refers to 110kV and above power lines.

Q:What are the general requirements for working on distribution equipment?: Common type cable connector used in power distribution equipment

Q:Power distribution equipment should be prepared before the blackout?: after the high and low voltage power failure, the work must be carried out before the first inspection

Q:Distribution system equipment classification: Special equipment used in a certain industry, such as artillery, automatic teller machine, steel making furnace, etc.

Q:What is the difference between power supply and distribution: The two is the integration of power generation and power supply.

Q:An introduction to the interpretation of flexible AC transmission systems: The series compensation device such as thyristor controlled series capacitor (TCSC), thyristor controlled reactor (TCSR), static synchronous series compensator (SSSC), active power flow is mainly used to change the system of distribution, improve the system transmission capacity and transient stability etc.;

Q:Difference between distribution voltage and supply voltage: Supply voltage refers to the supply point of the line voltage or phase voltage.

Q:High and low voltage distribution equipment: Distribution equipment refers to a variety of power plants, substations and factories and enterprises in the low-voltage power distribution system for power, distribution and lighting of the complete sets of equipment.
