The transformer substation is a place for converting voltage and current, receiving electric energy and distributing electric energy in an electric power system. The substations in the power plant are step-up substations, which are used to boost up the electrical energy generated by the generator and feed it into the high-voltage network.
The high-voltage circuit breaker is used for controlling a high-voltage circuit and is one of important electrical components in the high-voltage circuit. The circuit breaker is used for switching on or off a circuit in normal operation, and a fault condition rapidly breaks the circuit under the action of a relay protection device and reliably switches on short-circuit current under special conditions (such as automatic reclosing on a fault line). A high-voltage circuit breaker is a special appliance that switches on or off a high-voltage circuit under normal or fault conditions.
The main structure of the high-voltage circuit breaker is mainly divided into a flow guiding part, an arc extinguishing part, an insulating part and an operating mechanism part. The main types of the high-voltage switch are divided into an oil circuit breaker, an air circuit breaker, a vacuum circuit breaker, a sulfur hexafluoride circuit breaker, a solid gas production circuit breaker and a magnetic blow-out circuit breaker according to arc extinguishing media.
According to the operation property, the device can be divided into an electric mechanism, a pneumatic mechanism, a hydraulic mechanism, a spring energy storage mechanism and a manual mechanism.
An oil circuit breaker. The transformer oil is used as an arc extinguishing medium and is divided into two types, namely more oil and less oil.
Sulfur hexafluoride circuit breakers. The inert gas sulfur hexafluoride is used for arc extinction, and the high insulating property of the inert gas sulfur hexafluoride is used for enhancing the insulation between the contacts.
A vacuum interrupter. The contact is sealed in a high-vacuum arc extinguishing chamber, and the arc is extinguished by utilizing the high-vacuum insulating property.
An air circuit breaker. The arc is extinguished by the compressed air flowing at high speed.
Solid gas production circuit breaker. The arc is extinguished by gas decomposed from solid gas-generating substance under the action of high temperature of electric arc.
Magnetic blow-out circuit breaker. When the circuit is broken, the electric arc is rapidly stretched by the electromagnetic force generated by the large current flowing through the arc quenching device, sucked into the magnetic arc-extinguishing chamber and cooled and extinguished.
In the daily operation in-process of transformer substation, the indoor high voltage circuit breaker operation hand (hold) of transformer substation generally establishes at cubical switchboard body position, when the remote control operation device breaks down and can not operate, fortune dimension personnel receive the operating command after, have to face high voltage circuit breaker and operate on the spot, because there is the risk of explosion in the twinkling of an eye high voltage circuit breaker deciliter, fortune dimension personnel will bear very big personal risk.
