Abstract
The utility model discloses a box upper band interlocking device's box transformer, box door plant inboard sets up the slide, and the slide passes through the pull rod to be connected with transformer box body door roof beam, and travel switch fixes on transformer box body door roof beam, and the pull rod on the slide passes transformer box body door roof beam to be connected with travel switch break contact, travel switch make contact and breaker open operation winding connection. The utility model discloses install slide and pull rod on the box door plant, triggered travel switch, travel switch and breaker open operation winding connection through slide and rod structure to open control through the door plant in box transformer frequency response's break -make, reduced operating personnel's contact risk, protected operating personnel's personal safety, just the utility model discloses simple structure, operation, simple to operate, the user demand of satisfying the customer that can be better is convenient for promote in the industry and use.
Description
Technical field
The utility model belongs to box type transformer manufacture technology field, particularly relates to the box type transformer with interlock on a kind of casing.
Background technology
Traditional transformer concentrates design in box-type shell by box type transformer (being usually called for short " case change "), have that volume is little, lightweight, low noise, low-loss, high reliability, be widely used in the place such as residential quarters, commercial center, light station, airport, factories and miness, enterprise, hospital, school.。
The box-type substation transformer room rate that breaks down is lower, not needing frequent open operation, when need enter transformer room when breaking down, must ensure transformer power-off, to ensure the personal safety of maintenance worker.Present blanket box type transformer, whether when workman overhauls, be energized regardless of in transformer room, cabinet door is all very easily be opened, if do not have power-off in transformer room, is so just easy to cause workman to open by mistake cabinet door, causes by high-voltage electric injury.
Summary of the invention
The purpose of this utility model is to provide the box type transformer with interlock on a kind of casing, with solve above-mentioned workman overhaul box type transformer time, if there is no power-off in transformer room, easily cause workman to open by mistake chamber door, cause by the problem of high-voltage electric injury.
In order to realize the purpose of this utility model, the utility model provides the box type transformer with interlock on a kind of casing, comprise transformer-cabinet, transformer-cabinet door beam, casing door-plate, travel switch, circuit breaker in transformer room, inside described casing door-plate, slideway is set, slideway is connected with transformer-cabinet door beam by pull bar, described pull bar and slideway are slidably connected, described travel switch is fixed on transformer-cabinet door beam, pull bar on slideway is connected with travel switch break contact through transformer-cabinet door beam, described travel switch make contact is connected with breaker open operation coil, described circuit breaker is connected with transformer.
Wherein, described travel switch is bolted on transformer-cabinet door beam.
Wherein, described pull bar is N-type.
The utility model; compared with prior art; casing door-plate slideway and pull bar have been installed; travel switch is triggered by slideway and Tiebar structure; travel switch is connected with breaker open operation coil; thus the break-make of transformer frequency response in casing is controlled by the unlatching of door-plate; reduce the contact risk of operating personnel; protect the personal safety of operating personnel; and the utility model structure is simple, operation, easy for installation; the user demand of client can better be met, be convenient to industrially promotion and application.
Accompanying drawing explanation
Fig. 1 is the first structural representation of the present utility model;
Fig. 2 is the second structural representation of the present utility model;
In figure, 1-transformer-cabinet door beam, 2-travel switch, 3-transformer, 4-transformer-cabinet, 5-casing door-plate, 6-slides into, 7-N type pull bar, 8-breaker open operation coil, 9-travel switch break contact.
Embodiment
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly understand, below in conjunction with embodiment, the utility model is further elaborated.Should be understood to specific embodiment described herein only in order to explain the utility model, be not limited to protection range of the present utility model.
As Fig. 1, shown in Fig. 2, the utility model provides the box type transformer with interlock on a kind of casing, comprise transformer-cabinet 4, transformer-cabinet door beam 1, casing door-plate 5, travel switch 2, circuit breaker 3 in transformer room, inside described casing door-plate 5, slideway 6 is set, slideway 6 is connected with transformer-cabinet door beam 1 by pull bar 7, described pull bar 7 is slidably connected with slideway 6, described travel switch 2 is fixed on transformer-cabinet door beam 1, pull bar 7 on slideway 6 is connected with travel switch break contact 9 through transformer-cabinet door beam 1, described travel switch 2 make contact is connected with breaker open operation coil 8, described circuit breaker is connected with transformer 3.
In a preferred embodiment, described travel switch 2 is bolted on transformer-cabinet door beam 1.
In a preferred embodiment, described pull bar 7 is N-type.
When overhauling transformer, no matter transformer room's whether power-off, as long as opened by casing door-plate, namely can trigger interlock, carry out auto-breaking, convenient, safety, quick, meets the user demand of user.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
