Abstract
The utility model provides an outdoor high-voltage demarcation vacuum circuit breaker. When a T-joint branch circuit of a 10kV overhead power distribution line breaks down, an outlet switch of a transformer substation trips. The outdoor high-voltage demarcation vacuum circuit breaker includes a shell (1). An inlet/outlet wire sleeve (2) is installed on the lower part of the shell. An insulating box (3) is installed on the lower part in the shell. A vacuum arc extinguishing chamber (4) is installed in the insulating box. The vacuum arc extinguishing chamber is connected with the inlet/outlet wire sleeve (2). The vacuum arc extinguishing chamber is connected with an insulation pull rod (5). The insulation pull rod (5) is connected with a main shaft (6). A zero-sequence current transformer (7) and an A/C phase current transformer (8) are installed in the shell. The shell is connected with the upper shell (9). An anti-explosion device (10) is installed on the upper cover. The upper cover is connected with the hoisting device (11). A fixed cross rod (12) is installed on the hoisting device. The utility model is suitable for a vacuum circuit breaker.
Description
technical field:
the utility model relates to a kind of outdoor high-voltage demarcation vacuum circuit breaker.
background technology:
when 10KV overhead distribution T connects branch line or terminal temperature difference inside and breaks down, cannot rationally adjust because of its service entrance switch protection operation time limit and transformer station outlet switch protection time coordinations time, will cause transformer station's outlet switch to trip.If nature of trouble is permanent, transformer station overlaps unsuccessful, and the Local Accidents in Middle Voltage circle will make whole piece 10KV distribution line have a power failure.If at the T place of connecing or user side (responsibility separation) install a user demarcation switch (being commonly called as house dog), through judgement confirm in user circle to break down faults such as () overcurrent, short circuit, single-phase earthings, automatically by Fault Isolation, can guarantee the normal electricity consumption of non-faulty section user.
utility model content:
the purpose of this utility model is to provide a kind of outdoor high-voltage demarcation vacuum circuit breaker.
above-mentioned object realizes by following technical scheme:
a kind of outdoor high-voltage demarcation vacuum circuit breaker, its composition comprises: shell, at described outer casing underpart, inlet-outlet sleeve is installed, in described shell, bottom is provided with insulation booth, in described insulation booth, vacuum interrupter is installed, described vacuum interrupter is connected with described inlet-outlet sleeve, described vacuum interrupter is connected with insulated tension pole, described insulated tension pole is connected with main shaft, in described shell, zero sequence current mutual inductor is installed, A/C phase current mutual inductor, described shell is connected with upper cover, cover on described explosion-protection equipment is installed, described upper cover is connected with boom hoisting, fixing cross-arm is installed on described boom hoisting.
described outdoor high-voltage demarcation vacuum circuit breaker, described explosion-protection equipment is Z-shaped plate, on described in the bottom plate of described Z-shaped plate is bolted on, cover, sealing between described shell and described upper cover adopts punch forming groove to be tightly connected, described inlet-outlet sleeve employing epoxy resin and silicon rubber are integrated poured, and A, the C two-phase of described A/C phase current mutual inductor adopt turning sleeve pipe.
beneficial effect:
the utlity model has fault detection capability, protection control function and communication function, can reliably judge, detect milliampere level zero-sequence current and phase fault electric current in boundary and out-of-bounds, realize automatic single phase ground fault and the phase fault of excising.
the utility model adopts vacuum extinction and SF6 gas as dielectric, and overall sealing performance is good, and the SF6 gas that inside is filled with does not leak, and is not affected by the external environment.
reliability of Microprocessor of the present utility model and stability have improved 2 to 4 times than domestic traditional spring operating mechanism; Contacting between the axle of major loop and cover adopted interior receipts to open formula watch chain structure outward, and the contact resistance of major loop is little, and temperature rise is low.
the utility model adopts the sealing of punch forming groove, and output pointer axle adopts double-deck "O"-ring sealing, and inlet-outlet sleeve is integrated poured, ensures good air-tightness.
