Abstract
The utility model provides a fuse interlocking device which can cause the opening of a vacuum switch when the fuse is melted. The fuse interlocking device comprises a tripping linkage crank arm provided with a pressure block, a guide block and a micro switch mounting plate. An interlocking rod is arranged under the pressure block. The interlocking rod is inserted into the guide block and the micro switch mounting plate. An interlocking crank arm is arranged on the interlocking rod positioned above the micro switch mounting plate. A return spring is arranged between the interlocking crank arm and the micro switch mounting plate. The return spring is sleeved onto the interlocking rod. A locking pressure plate is arranged on the interlocking crank arm. The locking pressure plate can be locked with a closing half shaft crank arm. According to the fuse interlocking device of the utility model, an interlocking shaft presses the interlocking rod when the fuse is melted; a bolt pin on the interlocking rod drives the interlocking crank arm to make the locking plate block the closing haft shaft crank arm, so that the closing cannot be carried out; and the interlocking rod pushes and opens a crank arm on an opening haft shaft at the same time, so that the switch is opened to complete the interlocking.
Description
Technical field
The utility model relates to a kind of fuse equipment, especially a kind of fuse interlock.
Background technology
The vacuum switch of existing 24KV withdraw-type only has circuit breaker, and the device that its mechanism does not interlock with fuse can't impel the vacuum switch separating brake during fuse blows.
The utility model content
The purpose of this utility model provides a kind of fuse interlock that can impel the vacuum switch separating brake when fuse blows.
Realize the fuse interlock of the utility model purpose, comprise the dropout interlock connecting lever, guide pad and the sensitive switch mounting panel that are provided with briquetting, described briquetting below is provided with blocking lever, and described blocking lever inserts in guide pad and the sensitive switch mounting panel; On the described blocking lever, be positioned at sensitive switch mounting panel top, be provided with the interlocking connecting lever, be provided with return spring between described interlocking connecting lever and the sensitive switch mounting panel, described return spring is enclosed within on the blocking lever, described interlocking connecting lever is provided with the locking pressing plate, described locking pressing plate can with the locking of combined floodgate semiaxis connecting lever.
The utility model beneficial effect is as follows: fuse interlock of the present utility model, interlocking shaft presses blocking lever when fuse blows, bolt pin on the blocking lever drives the interlocking connecting lever makes latch plate block combined floodgate semiaxis connecting lever, and then can't close a floodgate, blocking lever backs down the connecting lever on the separating brake semiaxis simultaneously, impel the switch separating brake, finish interlocking.
Description of drawings
Fig. 1 is the structural representation of fuse interlock of the present utility model.
Fig. 2 is the front view of fuse interlock of the present utility model.
Embodiment
Embodiment of the present utility model is as follows: as shown in Figure 1, 2, fuse interlock of the present utility model, comprise the dropout interlock connecting lever 7, guide pad 2 and the sensitive switch mounting panel 6 that are provided with briquetting 8, described briquetting 8 belows are provided with blocking lever 1, and described blocking lever 1 inserts in guide pad 2 and the sensitive switch mounting panel 6; On the described blocking lever 1, be positioned at sensitive switch mounting panel 6 tops, be provided with interlocking connecting lever 4, be provided with return spring 3 between described interlocking connecting lever 4 and the sensitive switch mounting panel 6, described return spring 3 is enclosed within on the blocking lever 1, described interlocking connecting lever 4 is provided with locking pressing plate 5, described locking pressing plate 5 can with the locking of combined floodgate semiaxis connecting lever.
The operation principle of fuse interlock of the present utility model is as follows: when fuse blows, the dropout interlock connecting lever 7 of striker striker fuse, briquetting 8 is to pressing down blocking lever 1, driving interlocking connecting lever 4 and locking pressing plate 5 is rotated down, with the locking of combined floodgate semiaxis connecting lever, simultaneously return spring 3 downward energy storage.After fuse was removed fault, return spring 3 was upwards released energy, and blocking lever 1 drives interlocking connecting lever 4 and locking pressing plate 5 rotates up, with combined floodgate semiaxis connecting lever unlocking, and simultaneously fuse tripping interlock connecting lever 7 returns.Wherein guide pad 2 and sensitive switch mounting panel 6 play the positioning action of blocking lever 1.
Embodiment recited above is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; design under the spiritual prerequisite not breaking away from the utility model; various distortion and improvement that the common engineers and technicians in this area make technical solutions of the utility model all should fall in the definite protection range of claims of the present utility model.
