Abstract

A secondary lateral-bare live-wire contact insulating protecting cover of a ten-kilovolt transformer relates to an insulating protecting cover for the transformer bare live-wire contacts. The utility model is characterized in that the protecting cover (1) is a hollow insulating shell with the wall thickness H, the upper portion of the protecting cover (1) is a conical table shape (1-1), the middle portion of the protecting cover (1) is a column shape (1-2), the side of the column shape is provided with a trumpet shape (1-3-3) at a root, the middle portion is the column shape (1-3-1), and the tail portion is provided with a lateral cover (1-3) in the conical table shape (1-3-2). The utility model has the advantages of simple structure, easy mounting, and low manufacture cost, and adopts the weather-ability (modified) polyethylene insulating material, the safe insulating performance is good, and the accidents that personal bodies are electrically shocked by errors, and the charged body is caused by thrown objects to produce short-circuit, service interruption, and damage to the equipment and the like can be effectively avoided, and the severe accidents that the current leakage and the loss of electric quantity and the like are caused by ice coating, snow coating, heavy rain, acid rain, wind erosion, and solar eclipse can also be prevented.

Description

10 kv transformer secondary sides expose charged contact insulation protective hood

Technical field: the utility model relates to a kind of insulation protective hood that the exposed charged contact of transformer is used.

Background technology: the coverage rate of present 10 KV distribution networks is very big, because it approaches power consumption equipment and electricity consumption crowd most, but also be the weakest link of electric power system power grid security, its reason is to exhale the exposed charged contactor density of the highly lower transformer platform of title big apart from ground, quantity is many, and these exposed charged contact average departure ground have only 4～6 meters, personal error shock accident and the artificial phase fault of throwing out discards without care and causing very easily take place, ground connection, equipment scaling loss and large area blackout, icing in addition, snowberg and heavy rain, acid rain, wind erosion, solar eclipse also can cause ground connection and electric current to leak, make the line loss electric weight, cause economic loss.

Summary of the invention: the utility model is the exposed charged contact insulation protective hoods of a kind of 10 kv transformer secondary sides of development, make its exposed charged contact place of secondary side to 10 kv transformers have the security protection effect, eliminate simultaneously because the hidden danger that exposed contact causes, improve the safe and reliable rate of operation of power networks, the utility model comprises protective cover 1; Protective cover 1 is the hollow insulation shell that a wall thickness is H, the top of protective cover 1 is frustum 1-1, the middle part of protective cover 1 is column 1-2, and being provided with root in the side of column 1-2 is that horn-like 1-3-3, middle part are that column 1-3-1, afterbody are the side cover 1-3 of frustum 1-3-2.The utlity model has simple in structure, advantage of low manufacturing cost, what it adopted is weatherability (modification) polyethylene insulating material, so its safe insulation performance is good, and it also has globality does not need any connector and the fixing easy-to-install characteristics of cassette.Protective cover 1 is divided into red, yellow, green three kinds of colors and is complementary with the charged contact of transformer three-phase, be convenient to identification and change, can prevent the generation of personal error shock accident and parabolic effectively and cause accidents such as electrified body is short-circuited, power failure, device damage, can also prevent because of icing, snowberg and heavy rain, acid rain, wind erosion, solar eclipse to the electric current that is caused leak, serious accident such as loss electric weight takes place.

Description of drawings: Fig. 1 is a front view of the present utility model, Fig. 2 is the vertical view of Fig. 1, Fig. 3 is the cut away left side view of Fig. 1, Fig. 4 is application state figure of the present utility model, Fig. 5 is the front view of embodiment four, Fig. 6 is the vertical view of Fig. 5, and Fig. 7 is the sectional view of Fig. 5, and Fig. 8 is the application state figure of embodiment four.

Embodiment one: present embodiment comprises protective cover 1; Protective cover 1 is that a wall thickness is the hollow insulation shell of H=2.0～2.2 millimeter, the top of protective cover 1 is frustum 1-1, the middle part of protective cover 1 is column 1-2, and being provided with root in the side of column 1-2 is that horn-like 1-3-3, middle part are that column 1-3-1, afterbody are the side cover 1-3 of frustum 1-3-2.What the protective cover 1 in the present embodiment adopted is weatherability (modification) polyethylene insulating material, and it has good insulation preformance, ageing-resistant characteristics.Protective cover 1 is enclosed within the outside of charged contact 2.

Embodiment two: that present embodiment and embodiment one are different is fin 1-5 in the lower end of column 1-2 has additional, and interior fin 1-5 plays the role of positioning, and makes its insulating protection effect better.

Embodiment three: the inner cavity size of present embodiment protective cover 1 is slightly larger than the flake seal gasket 2-8 place that the overall dimension of charged contact 2, interior fin 1-5 are arranged on charged contact 2.

Embodiment four: present embodiment and embodiment one, two, three are different is to have additional on the column 1-2 of protective cover 1 and boss 1-6 that side cover 1-3 middle part is contour; The root of side cover 1-3 is that horn-like 1-3-3, middle part are that flat column 1-3-1, afterbody are flat frustum 1-3-2.Other composition is identical with embodiment one, two, three with annexation.
