Abstract
The utility model discloses a combined circuit breaker used on a pole, composed of a vacuum switch, a isolating switch, a switch operating mechanism, an interlock mechanism and an induction microwave applicator, wherein, the vacuum switch is arranged on a porcelain sleeve of the isolating switch to reduce the volume of the circuit breaker; a lightning arrester is arranged in a porcelain sleeve at the other side of the isolating switch to prevent lightning strike; a vacuum arc-extinguishing chamber is additionally provided with an insulation protective layer for prevent external force damage and increase creepage distance; the induction microwave applicator can heat the vacuum switch to cause the circuit breaker to work normally under the environment of +50DEG. C-45DEG. C. The utility model has the advantages of compact structure, convenient installation, small size and favorable performance.
Description
The utility model relates to a kind of circuit breaker that is used on the high-tension apparatus.
At present, be used for the vacuum circuit-breaker on the 10KV overhead wire, vacuum interrupter is installed in the iron case, and spring mechanism is contained in the casing outside, and this vacuum circuit-breaker volume is bigger, inconvenience is installed, the easy oil impregnate of oil-filled casing, maintenance is big, poor performance at low temperatures, can only be at+50 ℃--work under 25 ℃ of environment, the incompatibility the Northeast uses.
The purpose of this utility model is to provide composite type vacuum circuit-breaker on a kind of post, have the multiple function of load operation, fault trip of circuit, and volume is little, and is easy for installation, is applicable to low temp area.
The utility model is made up of vacuum switch, isolating switch, switch operating mechanism, interlocking device and induction microwave applicator, and the vacuum interrupter of vacuum switch installs insulating sleeve outward additional, and the centre is passed by the insulation link rod.Isolating switch is made up of disconnecting link, porcelain bushing and base, and vacuum switch is arranged on the top of a side porcelain bushing, and the zinc oxide lightning rod is installed in the opposite side porcelain bushing.Switch operating mechanism is that a spring mechanism is made up of electromagnetism trip component and electromagnetism combined floodgate element, is arranged in the isolating switch base.
The interior microwave antenna of installing of insulating sleeve of current transformer vacuum switch is installed between vacuum switch and the isolating switch, and the isolating switch base position is provided with interlocking device.The induction microwave applicator is a radio device, be installed in the appropriate location of switch, working power line taking road high voltage electric field, supply with microwave generator through amplifying rectification, the microwave that sends receives by microwave antenna, to the vacuum interrupter heating, make circuit breaker at+50 ℃--operate as normal under 45 ℃ of environment.
Advantage of the present utility model is:
(1) vacuum switch and isolating switch are installed together, and have reduced the volume of vacuum circuit-breaker;
(2) in the isolating switch porcelain bushing lightning rod is set, avoids damage to crops caused by thunder in order to on-pole switch equipment such as protective circuit breaker, isolating switches.
(3) vacuum interrupter installs insulating protective layer outward additional, prevents the external force damage, increases creepage distance.
(4) adopt induction microwave applicator heating, vacuum arc control device, widen the cryogenic property of circuit breaker, make vacuum switch at+50 ℃--operate as normal under 45 ℃ the environment.
The utility model is described in further detail below in conjunction with accompanying drawing;
Fig. 1 is a front view of the present utility model;
Fig. 2 is a left view of the present utility model;
Fig. 3 is the fundamental diagram of induction microwave applicator.
The disconnected device of composite type vacuum is made up of vacuum switch 1, isolating switch, switch operating mechanism 3, interlocking device 12 and induction microwave applicator on the post, isolating switch is made up of disconnecting link 5, porcelain bushing 6 and base 7, porcelain bushing 6 tops are provided with vacuum switch to be made up of vacuum interrupter and insulation link rod 8, and vacuum interrupter installs the insulating sleeve that plastics or silicon rubber are made outward additional; Zinc oxide lightning rod 9 is installed in the porcelain bushing 6, vacuum is opened between sky 1 and the isolating switch current transformer 10 is set, and microwave antenna 11 is arranged in the vacuum switch insulating sleeve, and switch operating mechanism 3 is arranged in the isolating switch base 7,12 is interlocking device, prevents the operation of staff's on-load.
The composite type vacuum circuit-breaker is the outdoor on-load switch of a kind of 10KV on the post; play control and protective effect; when line current surpasses definite value; produce electric current by current transformer and make circuit breaker trip by the trip component in the switch operating mechanism; but the operating mechanism manual brake separating of this switch also can be used as the executive component of remote control.
Induction microwave applicator working power line taking road high voltage electric field, supply with microwave generator through amplifying rectification, this device is provided with temp autocontrolled loop, when the switch working temperature is lower than-20 ℃, the work of induction microwave generator, the heating, vacuum switch makes normal operation of circuit breaker, when the switch working temperature was higher than 20 ℃, heater was out of service automatically.
Claims (1)
1, composite type vacuum circuit-breaker on a kind of post, by vacuum switch (1), isolating switch, switch operating mechanism (3), interlocking device (12) and induction microwave applicator are formed, it is characterized in that: the vacuum switch that vacuum interrupter installs the insulating sleeve composition outward additional is arranged on porcelain bushing (6) top of isolating switch, the zinc oxide lightning rod is installed in porcelain bushing (6) opposite side, current transformer (10) is set between vacuum switch and the isolating switch, microwave burst at the seams (11) be arranged in the insulating sleeve, the base position of isolating switch is provided with switch operating mechanism (3) and interlocking device (12).
