Description

Novel outdoor high-voltage column circuit breaker protection isolation cover

Technical Field

The utility model relates to a can carry out isolation protection to circuit breaker on the outdoor high-voltage column effectively, have good ventilation, heat dissipation again, circuit breaker protective isolation cover on the novel outdoor high-voltage column of anti-wind function belongs to high-voltage column cage and makes the field.

Background

CN2452106Y, name "high-voltage binding post safety protection casing", including the cover body and wire protective sheath, its characterized in that: the cover body and the lead protective sleeve are of an integral structure, an opening is formed in the lower portion of the integral structure, the high-voltage wiring terminal and the lead can be placed in the opening, and a bottom plate which is connected with the opening in an openable mode is arranged at the opening of the lead protective sleeve. By adopting the scheme, the high-voltage wiring terminal can be well protected, and can prevent electricity stealing, electric shock and oxidation corrosion, prevent interphase short circuit caused by birds and animals, and is convenient to use and install. The method has the following defects: the high-voltage wiring terminal is covered by the cover body, so that the protection effect is achieved, but the covered high-voltage wiring terminal is not ventilated, and heat cannot be dissipated, so that a poor effect is achieved.

Disclosure of Invention

The design purpose is as follows: on the basis of the background technology, a novel outdoor high-voltage pole-mounted circuit breaker protection isolation cover which can effectively isolate and protect a high-voltage pole and has good ventilation, heat dissipation and wind resistance functions is designed.

The design scheme is as follows: in order to realize the design purpose of the utility model. The utility model discloses in structural design, left side board and right side board relative interval distribution and left side board on with the right side board on open and have a plurality of ventilation holes to constitute convection current ventilation support wall body, left side board and right side board constitute open cage main part with top cap back connection, play and both keep apart three high voltage terminal, and rain-proof aquatic and birds faecal purpose, the intermediate lamella is located between left side board and the right side board and even as an organic whole with left side board and right side board, both increased the bulk strength of cage simultaneously, it has the shape of falling U-shaped hole to open in intermediate lamella middle part lower part, this shape of falling U-shaped hole can make the cage fix well on high voltage terminal through the connecting piece, it is the interval cooperation to open on the intermediate lamella and intermediate lamella upper end and the top cap simultaneously, make the cage have fine ventilation and anti-wind performance, the not enough that the background art exists have been avoided.

The technical scheme is as follows: the utility model provides a novel circuit breaker protection cage on outdoor high-voltage column, left side board and right side board are interval distribution relatively, and left side board upper end and right side board upper end are connected with the top cap respectively, and the intermediate lamella is located between left side board and right side board and the intermediate lamella is connected with left side board and right side board.

Compared with the prior art, the utility model, both realized the isolation and the protection to a plurality of high voltage terminal, avoided rainwater, bird droppings and other filths to the influence of high voltage terminal again, had good ventilation performance again simultaneously, prolonged the life of high voltage terminal and the fail safe nature of work greatly.

Detailed Description

Example 1: reference is made to figures 1-3 of the drawings. The utility model provides a novel circuit breaker protective isolation cover on outdoor high-voltage column, left side board 2 and 4 relative interval distributions of right side board, and 2 upper ends of left side board and 4 upper ends of right side board are connected with top cap 1 respectively, there is hem portion left side board 2 and 4 upper ends of right side board promptly, this hem portion bonds or bolt or screwed connection with top cap 1, intermediate lamella 3 is located between left side board 2 and right side board 4 and intermediate lamella 3 is connected with left side board 2 and right side board 4, the mode of connection can be the bonding, also can be bolted connection or screwed connection. When the bolt connection is adopted, the two sides of the middle plate 3 are provided with folded edges. The intermediate plate is provided with a hoop, and the hoop and the high-voltage wiring terminal form hoop connection so as to fix the isolation hood. The lower part of the middle plate 3 is provided with an inverted U-shaped hole 5, and the middle plate 3 is provided with a plurality of ventilation holes 6. Left side board 2 and right side board 4 look sideways and are the concave structure and left side board 2 and right side board 4 go up to open has a plurality of ventilation holes 6. The upper end of the middle plate 3 is matched with the top cover 1 at a distance. The isolation and fixation between the isolation cover and the high-voltage binding post can be realized by adopting non-metal bolts, also can adopt non-metal binding, and also can adopt a hoop to fix the isolation cover on the high-voltage binding post.

Example 2: on the basis of embodiment 1, when the middle plate 3 is two, one middle plate 3 is located between the left side plate 2 and the right side plate 4, one middle plate is located behind the left side plate 2 and the right side plate 4, and high-voltage terminal hoops (not shown) are respectively arranged on the middle plates.

It is to be understood that: although above-mentioned embodiment is right the utility model discloses a design has done more detailed word description, but these word descriptions, are only right the utility model relates to a simple word description of idea, rather than right the utility model relates to a restriction of idea, any do not surpass the utility model relates to a combination, increase or the modification of idea all fall into the utility model discloses a within the protection scope.
