Description
Technical field
The utility model is specifically related to a kind of double power supply automatic transfer switch.
Background technology
At present, many industries and the department reliability to power supply has very high requirement, and in order to ensure the continuity of powering, it is electric power supply that many important occasions all have employed double power supply automatic transfer switch.As the indispensable device that electric energy switches, its Main Function is, when normal power source breaks down, can automatically switch to stand-by power supply and continue load supplying, automatically can carry out anti-switching after power up is normal, thus meets the requirement of low-voltage power supply system to electrical source exchange.Existing a kind of double power supply automatic transfer switch is provided with a transparency cover by moving contact corresponding on the housing of contact system and fixed contact place, operating personnel can observe the operating state of moving contact by transparency cover, thus operating personnel can grasp this double power supply automatic transfer switch in time whether is in normal operating conditions.This double power supply automatic transfer switch is in Long-Time Service process, transparency cover is owing to being subject to the impact of electric arc, therefore, the observing effect of transparency cover reduces greatly, thus this transparency cover needs often to change, but the structural design of the housing of the double power supply automatic transfer switch of existing this band transparency cover is unreasonable, cause the transparency cover on this housing more loaded down with trivial details in installation and removal, thus greatly reduce the operating efficiency of attendant.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, provide a kind of structure simple, safeguard convenient and a kind of double power supply automatic transfer switch of the operating state of moving contact can be observed.
For achieving the above object, the utility model adopts a kind of double power supply automatic transfer switch, comprise conversion equipment, contact system, described contact system comprises housing, be arranged on the fixed contact in housing, corresponding fixed contact place to be arranged in housing and to link the moving contact arranged with conversion equipment, on described housing, corresponding moving contact and fixed contact place are provided with a transparency cover, this transparency cover is arranged in the draw-in groove on housing, and the open end of draw-in groove is installed with a clamp, conflict on one end of transparency cover in one end of this clamp, and transparency cover is locked in draw-in groove by clamp, the upper surface of the other end of clamp is provided with an open hole, on described housing, corresponding transparency cover place is installed with a trim, this trim is provided with a square opening, the top of described transparency cover is sleeved in square opening.
The beneficial effect of said structure is: this double power supply automatic transfer switch by being provided with a transparency cover on the housing of contact system, when changing transparency cover, first trim is pulled down from housing, then clamp is pulled out in the draw-in groove of housing, thus the transparency cover in draw-in groove can be changed.The transparency cover of this vibrational power flow have structure simple, install or remove advantage easily, thus improve the operating efficiency of attendant.
Especially, the two ends of described trim are respectively arranged with a hole clipping, and the hole clipping place on two sidewalls of described housing described in correspondence is provided with a suitable boss, and described hole clipping is installed on and boss forms trim is connected with the buckle of housing.The mode that housing and the trim of this contact system adopt buckle to be connected connects, thus is convenient to the installation and removal of trim.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment stereogram.
Fig. 2 is the decomposing schematic representation of the utility model contact system.
Fig. 3 is the cutaway view of the utility model contact system.
Embodiment
As Fig. 1, 2, shown in 3, the utility model embodiment is a kind of double power supply automatic transfer switch, comprise conversion equipment 10, contact system 20, described contact system 20 comprises housing 21, be arranged on the fixed contact 31 in housing 21, corresponding fixed contact 31 place to be arranged in housing 21 and to link the moving contact 30 arranged with conversion equipment 10, on described housing 21, corresponding moving contact 30 and fixed contact 31 place are provided with a transparency cover 22, this transparency cover 22 is arranged in the draw-in groove 211 on housing 21, and the open end of draw-in groove 211 is installed with a clamp 23, conflict on one end of transparency cover 22 in one end of this clamp 23, and transparency cover 22 is locked in draw-in groove 211 by clamp 23, the upper surface of the other end of clamp 23 is provided with an open hole 231, by being provided with open hole on clamp, thus be convenient to the dismounting of clamp, on described housing 21, corresponding transparency cover 22 place is installed with a trim 24, this trim 24 is provided with a square opening 241, the top of described transparency cover 22 is sleeved in square opening 241.The two ends of described trim 24 are respectively arranged with a hole clipping 242, hole clipping 242 place on two sidewalls of described housing 21 described in correspondence is provided with a suitable boss 212, and described hole clipping 242 is installed on and boss 212 forms trim 24 is connected with the buckle of housing 21.The mode that housing and the trim of this contact system adopt buckle to be connected connects, thus is convenient to the installation and removal of trim.Trim, by being provided with a transparency cover on the housing of contact system, when changing transparency cover, first being pulled down from housing, then being pulled out in the draw-in groove of housing by clamp by this double power supply automatic transfer switch, thus the transparency cover in draw-in groove can be changed.The transparency cover of this vibrational power flow have structure simple, install or remove advantage easily, thus improve the operating efficiency of attendant.
