Description
Technical Field
The utility model relates to a circuit breaker technical field especially relates to a permanent magnetism formula intelligence high pressure vacuum circuit breaker.
Background
The vacuum circuit breaker is a mechanical switch, i.e. the connection and disconnection of the circuit are realized by the mechanical movement of the contact, as in the common alternating current circuit breaker, but the difference is that the contact of the vacuum circuit breaker is sealed in vacuum, and the vacuum medium with excellent performance is used as an insulation isolation and arc extinguishing means, so that the vacuum circuit breaker has the advantages of higher working voltage, short arcing time, less contact electrical wear, no oxidation on the surface of the contact and the like.
Some high-voltage vacuum circuit breakers all set up on outdoor wire pole, when touchhing big snow weather, snow is piled up on the circuit breaker, can have a great pressure to the circuit breaker, in case snow exceeds the scope of bearing of circuit breaker to the pressure of circuit breaker, the circuit breaker can receive the damage of different degrees, for example wiring department crust breaks or the kneck is not hard up, this kind of condition is especially great in the snow volume in the north, perhaps more outstanding when the number of times of snowing is more, and simultaneously, snow makes the circuit breaker casing production gap easily to the pressure of circuit breaker, when snow melts, melt the water that produces and easily flow into the circuit breaker casing and cause the damage to circuit breaker internal element.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a permanent magnetism formula intelligence high pressure vacuum circuit breaker just in order to solve above-mentioned problem.
The utility model discloses a following technical scheme realizes above-mentioned purpose:
the utility model provides a permanent-magnet type intelligence high pressure vacuum circuit breaker, includes the circuit breaker body, circuit breaker body lower part both sides fixed mounting respectively have a brace table, a brace table upper surface fixed mounting respectively has the support frame, fixed mounting has between the support frame and shelters from the frame, shelter from the frame and cover the circuit breaker body.
Preferably: the shielding frame is formed by assembling a plurality of shielding plates, the shielding plates are arc-shaped plates, two adjacent shielding plates are stacked in a crossed mode, and a ventilation gap is formed.
Preferably: the support frame is door-shaped.
Compared with the prior art, the beneficial effects of the utility model reside in that: the reasonable setting shelters from the frame, owing to reserve the ventilation gap between the shielding plate, covers the circuit breaker body, has realized sheltering from under the normal radiating prerequisite of not influencing the circuit breaker and has got rid of most snow to extension fixture's life reduces the probability that the circuit breaker damaged.

Detailed Description
In the description of the present invention, it is to be understood that the terms "central", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing and simplifying the description, but not for indicating or implying that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus are not to be construed as limiting the invention, and further that the terms "first", "second", etc., are used only for descriptive purposes and are not to indicate or imply relative importance or imply the number of technical features being referred to, whereby the features defined as "first", "second", etc., may explicitly or implicitly include one or more such features, in the description of the present invention, "a plurality" means two or more unless otherwise specified.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; the two elements may be directly connected or indirectly connected through an intermediate medium, or the two elements may be connected through an intermediate medium, and the specific meaning of the above terms in the present invention can be understood by those skilled in the art through specific situations.
The present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1-3, a permanent magnet type intelligent high-voltage vacuum circuit breaker comprises a circuit breaker body 2, wherein two sides of the lower part of the circuit breaker body 2 are respectively and fixedly provided with a supporting table 1, the supporting tables 1 are used for fixing and supporting, the upper surfaces of the supporting tables 1 are respectively and fixedly provided with a supporting frame 3, the supporting frames 3 are used for fixing, shielding frames 4 are fixedly arranged between the supporting frames 3, the shielding frames 4 are used for shielding rain and snow, and the shielding frames 4 cover the circuit breaker body 2; the shielding frame 4 is formed by assembling a plurality of shielding plates, the shielding plates are arc-shaped plates, two adjacent shielding plates are stacked in a crossed manner, and a ventilation gap is formed to ensure normal ventilation in the shielding frame 4; the shape of the support frame 3 is door-shaped, so that rain and snow can freely slide off after falling on the shielding frame 4.
The working principle is as follows: during the use, non-sleet weather, the circuit breaker generates heat, because sets up ventilation gap between the shielding plate, can guarantee the circulation of air, can realize the normal heat dissipation of circuit breaker, when meetting sleet weather, receives sheltering from that frame 4 shelters from sleet and falls on sheltering from frame 4 landing, can not drench the circuit breaker, avoids circuit breaker body 2 to be drenched the risk of damage.
The circuit breaker body 2 is a universal standard or component known to those skilled in the art, and its structure and principle are known to those skilled in the art through technical manuals or through routine experimentation, and thus will not be described herein too much.
Having shown and described the basic principles, essential features and advantages of the invention, it should be understood by those skilled in the art that the present invention is not limited by the foregoing embodiments, which are merely illustrative, but rather are intended to cover various changes and modifications within the spirit and scope of the invention as defined by the appended claims.
