Abstract
The invention relates to a tank-type circuit breaker single-phase structure used in a power station device. A sulfur hexafluoride circuit breaker is an oil-free switch device taking SF6 gas as an insulation medium and an arc extinguishing medium and is not widely applied in intermediate voltage (35, 10KV). The tank-type circuit breaker single-phase structure comprises a group of wiring terminals (1), wherein each wiring terminal is connected with an upper grading ring (2), the upper grading ring is connected with a wire-outlet porcelain bushing (3), the wire-outlet porcelain bushing is connected with a lower voltage-equalizing pipe (4), the lower voltage-equalizing pipe is connected with a current transformer (12), the current transformer is connected with a shell (11), a unit arc extinguishing chamber (8) and a basin-type insulator (10) are arranged in the shell, the basin-type insulator is connected with a static contact (9), the arc extinguishing chamber is connected with a crank arm box (5), and the crank arm box is connected with a mechanism box (6). The tank-type circuit breaker single-phase structure is used for a tank-type circuit breaker used in the power station device.
Description
Technical field:
The present invention relates to the potting breaker phase structure used in a kind of power station equipment.
Background technology:
Sulfur hexafluoride breaker is the non-oil ultra high vacuum system switchgear utilizing SF6 gas to be dielectric and arc-extinguishing medium, its insulating properties and arc quenching characteristic are all much higher than oil-break, owing to its price is higher, and the application of SF6 gas, management, operation are all had higher requirements, therefore wide not enough in middle pressure (35,10KV) application。
Summary of the invention:
It is an object of the invention to provide the potting breaker phase structure used in a kind of power station equipment.
Above-mentioned purpose is realized by following technical scheme:
The potting breaker phase structure used in a kind of power station equipment, its composition includes: one group of terminals
Son, described binding post is connected with upper grading ring, described upper grading ring is arranged on outgoing line porcelain bushing pipe and connects, described outgoing line porcelain bushing pipe is connected with lower balance pipe, and described lower balance pipe is connected with current transformer, and described current transformer is connected with housing, unit arc-chutes, disc insulator are installed in described housing, described disc insulator is connected with static contact, and described arc-chutes are connected with crank arm box, and described crank arm box is connected with mechanism case.
The potting breaker phase structure used in described power station equipment, described housing is arranged on pedestal
On.
The potting breaker phase structure used in described power station equipment, described unit arc-chutes adopt two-way indulging to blow formula arc-chutes, during separating brake, by crank arm box drive mechanism, band dynamic air cylinder and moving contact motion.
The potting breaker phase structure used in described power station equipment, it is 6 gauge pressures, the SF6 gas of 20 DEG C that described unit arc-chutes are filled with nominal pressure, the control of hydraulic mechanism and operating element and circuit are all located in switch board, often it be furnished with hydraulic mechanism and a switch board mutually, can be individually operated, and three-phase operation can be carried out by electrical control.
Beneficial effect:
The advantage that present invention employs box bulk oil circuit, is fitted together chopper and transformer, compact conformation, antiseismic strong with antifouling capacity
The corona inception voltage of SF6 of the present invention is more much higher than air, and dielectric strength is unrelated with institute alive frequency, but what should arouse attention is field uniformity, impurity, the shape of electrode and scrambling etc., and the dielectric strength of SF6 is all had some strength.Insulation will be made a difference by the moisture in SF6 gas.In SF6, contained humidity makes SF6 reach more than 200 DEG C it is possible to produce to decompose in temperature when exceeding finite concentration, has Fluohydric acid. in the product of decomposition, and this is a kind of acids having severe corrosive and severe toxicity.Additionally, what edgewise insulation was also harmful to by the condensation of moisture.Therefore, in the electrical equipment of SF6, should strictly control the content of moisture.
Accompanying drawing illustrates:
Accompanying drawing 1 is the structural representation of the present invention.
