Description
Technical Field
The utility model belongs to the technical field of capacitor electricity taking, and particularly relates to a high-voltage switch with a built-in capacitor electricity taking device.
Background
The high-voltage switch (or called high-voltage circuit breaker) not only can cut off or close the no-load current and load current in the high-voltage circuit, but also can cut off the overload current and short-circuit current by the action of the relay protection device when the system is in fault, and has rather perfect arc extinguishing structure and enough current breaking capacity.
Existing high-voltage switches are mainly classified into two categories: strut-type high-voltage switches and box-type high-voltage switches.
The strut type high-voltage switch, such as the ZW32 type high-voltage switch, has large volume, and the adopted incoming line terminal, outgoing line terminal or ceramic insulating sleeve and the like are large-volume accessories, so the installation is not easy, the occupied area is large, and the application range is limited; and when the electric signal that needs to gather, can only adopt the external mode of mutual-inductor, the potential safety hazard is big.
The box type high-voltage switch, such as a ZW20 type high-voltage switch, is internally filled with SF6 gas, and has a gas leakage factor; under the action of electric arc and corona, SF6 gas is decomposed to produce low-fluorine compounds which can cause damage to the insulating material, and the low-fluorine compounds are extremely toxic gases and are not environment-friendly.
Therefore, no matter the support type high-voltage switch or the box type high-voltage switch has the defects, a novel high-voltage switch is needed, the function of the high-voltage switch can be realized, and the defects of the support type high-voltage switch and the box type high-voltage switch can be overcome.
Furthermore, in order to realize the protection function of the high-voltage switch, a voltage signal is generally required to be taken out from the high-voltage circuit, and whether no-load current and load current exist in the high-voltage circuit is judged through the measurement function of a voltage sensor; however, the existing voltage sensor is generally used for measuring a small voltage signal, and for an electrical signal with a large voltage, an auxiliary element such as a capacitor power-taking device is required to be used for converting a large voltage signal into a small voltage signal so as to achieve effective measurement.
