Abstract
The utility model discloses an outdoor high-voltage alternating-current vacuum breaker, which comprises a breaker body, a current transformer, disconnectors and a voltage transformer, the current transformer and the disconnectors are connected with the breaker body, the voltage transformer and the breaker body are mounted on the same support, the voltage transformer is respectively connected with the breaker body and the current transformer through insulated cables, and thereby an organic whole body is formed. The breaker body adopts a triphase-separated columniform structure, triphase primary loops are respectively mounted in insulating sleeves of the three phases, and when a single phase fails, triphase short-circuiting cannot be caused. Moreover, because all conductors are mounted in the insulating sleeves, the insulating property is greatly enhanced. Secondary wiring is optimized, conventional circular sockets are replaced by a junction box, and thereby the breaker is easy to repair, and is more suitable for automated distribution networks. The structure arrangement of the breaker is ingenious, and since the outdoor voltage transformer and the breaker are designed as an integrated structure, the utility model solves the power acquisition problem of distribution network automation.

Described breaker body and voltage transformer are installed on the same bearing, and described voltage transformer connects breaker body and current transformer by insulated cable respectively.
The PT power supply that described voltage transformer is just often said is installed together the voltage transformer and the breaker body of open air, and the collection of high voltage source is by the High-Voltage Insulation cable, not only reliably but also safety;
Preferably, above-mentioned current transformer is connected on the pole sidewall of described breaker body.
Described breaker body is made up of the interior three-phase pole that vacuum interrupter is housed, casing two parts that operating mechanism is housed.Described vacuum interrupter is installed in the insulating sleeve, with silicone rubber sleeve with the vacuum interrupter integral sealing in insulating sleeve, stopped because the short trouble that condensation causes.
Breaker body adopts the pole structure of three phase separation, the three-phase primary circuit is installed in the insulating sleeve of each phase, during single-phase breaking down, can not cause three-phase shortcircuit.
Electric conductor all is installed in the insulating sleeve, and insulation property improve greatly, has avoided the former dangerous accident that causes lack of standardization owing to pull lift action;
Described insulating sleeve adopts outdoor epoxy resin or silastic material to make, and has the dirty ability of excellent hydrophobicity and anti-soil, can be used for weather-proof requirement height, the abominable outdoor environment of service conditions.
Secondary connection is optimized in the casing of breaker body, and former aviation socket is changed to terminal box, and is convenient and reliable, and for ease of maintenaince, this structure and improvement are fit to the automation distribution more;
Comprehensive, the structure setting of above-mentioned circuit breaker makes the center of gravity of circuit breaker more near the center, is convenient to install.
After loading onto described isolating switch, constitute the circuit breaker of band isolating switch, total weight only is 100 kilograms, installs also more convenient.
The beneficial effects of the utility model are, outdoor voltage transformer and circuit breaker design are integral formula, little, the compact overall structure of volume, and insulation property are good, not only safety but also reliable;
Solved the relatively independent power supply of former circuit breaker and voltage transformer and gathered a difficult problem, overall structure is more reasonable, is convenient to install.
