Abstract
The utility model discloses an automatic discharge mechanism of a mine flame-proof type high-voltage vacuum power distribution device, which is used together with the high-voltage vacuum power distribution device. The self discharge mechanism is arranged in the casing of the mine flame-proof type high-voltage vacuum power distribution device, a conventional three-phase explosion-proof contact terminal and an insulating partition board are used for forming a main bus socket, a hinge shaft is arranged on the insulating partition board, the insulating partition board is movably connected to three metal discharging hooks in positions corresponding to the three-phase explosion-proof contact terminal through the hinge shaft, and a striking plate is further arranged at the bottom of each metal discharge hook. When the device is powered off, high voltage electricity can enter the earth automatically through the metal discharge hooks, the hinge shaft and a grounding wire, and the process of automatic discharge before equipment is opened can be achieved. The discharge mechanism has the advantages of simple and compact structure, original and unique conception, stable working performance and reliable discharge process, does not require individual operation, and is suitable for vigorous popularization.
Description
Technical field: the utility model relates to a kind of automatic discharge mechanism, especially relates to the matching used automatic discharge of a kind of and flameproof high-voltage vacuum distribution equipment mechanism.
Background technology: at present, the high-voltage vacuum distribution equipment that uses under the coal mine does not generally all have the mechanism of discharge automatically, so, device interior has the accumulation high voltage electricity when the device outage, when the maintenance personal opens equipment and keeps in repair, the high voltage electricity that is accumulated can cause that just the person wounds, there is employing to discharge manually for fear of described accident, but still there is potential safety hazard under the equipment state opening, and very easily cause the blast of gas and coal dust, will bring the heavy losses of loss of life or personal injury and national wealth inevitably.
Summary of the invention: the utility model is for a kind of automatic discharge mechanism of flameproof high-voltage vacuum distribution equipment for mining is provided, purpose is to solve not having owing to device is interior when discharging the mechanism opening maintenance automatically of existing in the prior art, the high voltage electricity of its inner accumulation can cause that just the person wounds, still there is potential safety hazard when taking to discharge manually, and easily cause the blast of gas and coal dust, still can bring the problem of the heavy losses of loss of life or personal injury and national wealth.
Scheme of the present utility model is as described below: this utility model comprises the main bus bar socket of being made up of explosion-proof contact of three-phase and insulating barrier, also comprise hinge, it is by a hinge is set on the insulating barrier of main bus bar socket, flexibly connect and the corresponding metal discharge hook of the explosion-proof contact position of three-phase through hinge, and be provided with in its bottom one hit firm and hard existing.
Described metal discharge hook is that a center and hinge flexibly connect, and an end buckle, the other end are fillet and the buckle end active connection lighter than the weight of rounded end.
The described plate that hits is a Z-shaped plate sheet that is provided with the inclination angle.
The beneficial effects of the utility model: this utility model is owing to taked said structure, when equipment is in the combined floodgate electriferous state, mechanism hits plate in progradation and the metal discharge hook bumps, and the explosion-proof contact of metal discharge hook and three-phase is thrown off, and equipment is in the charging operation state.When equipment is in the separating brake off-position, hit plate in this mechanism and separate with the metal discharge hook, metal discharge is hooked under the action of gravity and the explosion-proof contact of three-phase freely overlaps.High voltage electricity enters the earth automatically by metal discharge hook, hinge, earth connection, the automatic discharge process before the equipment of finishing is opened.The reliable goal of the invention that realizes.Also have simultaneously uniqueness simple and compact for structure, novel, stable work in work, discharge process reliable, advantage such as need not operate, be fit to widely popularize separately.
Description of drawings:
Fig. 1 is an automatic discharge of the present utility model mechanism separating brake discharge condition schematic diagram;
Fig. 2 is an automatic discharge of the present utility model mechanism combined floodgate running status schematic diagram.
Embodiment: by Fig. 1, the automatic discharge mechanism of a kind of flameproof high-voltage vacuum distribution equipment for mining shown in Figure 2, be arranged in the housing of flameproof high-voltage vacuum distribution equipment for mining, the main bus bar socket that it utilizes existing explosion-proof contact 1 of three-phase and insulating barrier 2 to form, one hinge 3 is set on the insulating barrier 2 of main bus bar socket, flexibly connect (hinged) and corresponding three the metal discharge hooks 4 in the explosion-proof contact of three-phase 1 position through hinge 3, described metal discharge hook 4 is that a center and hinge 3 flexibly connect an end buckle, the other end is fillet and the buckle end active connection lighter than the weight of rounded end.Also be provided with one in the bottom of metal discharge hook 4 and hit plate 5.The described plate 5 that hits is Z-shaped plate sheets that are provided with the inclination angle.Hit plate 5 bottoms and the cart stationary of carrying permanent-magnet breaker, when the permanent-magnet breaker divide-shut brake, the device operating mechanism is controlled dolly automatically together with permanent-magnet breaker with hit plate 5 move left and right, it when moving right "on" position, this moment, metal discharge hook 4 was thrown off with the explosion-proof contact 1 of three-phase, and permanent-magnet breaker is in has electricity in service.Be gate-dividing state when being moved to the left, metal discharge hook 4 and other part of hitting plate 5 and this discharge mechanism break away from, and metal discharge hook 4 impels the buckle end upwards freely to overlap with the explosion-proof contact of three-phase under action of gravity.High voltage electricity enters the earth by metal discharge hook 4, hinge 3, earth connection, the automatic discharge process before the equipment of finishing is opened.Thereby eliminated potential safety hazard, guaranteed maintenance personal's personal safety, prevented to cause the blast of gas and coal dust, avoided national wealth to suffer a loss.
