Abstract
The utility model discloses an armoured removing-type alternating-current switch metal sealed metering cabinet which comprises a cabinet body, wherein the cabinet body is provided with a line feed cable. The armoured removing-type alternating-current switch metal sealed metering cabinet is characterized by also comprising a handcart capable getting in and out of the cabinet body; a voltage transformer, a high-voltage fuse and a current transformer are fixed sequentially from top to bottom on the handcart; a moving contact is also fixedly arranged on the handcart; the moving contact is sequentially connected with the voltage transformer, the high-voltage fuse and the current transformer in series through a lead; a static contact which is matched with the moving contact is fixedly arranged in the cabinet body; and the line feed cable is connected with the static contact. According to the cabinet, because the voltage transformer, the high-voltage fuse and the current transformer are fixed on the handcart, the handcart can be pulled out from the cabinet body in maintaining, and the maintaining is not limited in a small inner space of the cabinet body, and thus the maintaining is relatively smooth, also an insulation cabinet is not required to be arranged at the front stage of the cabinet body, and a large amount of production cost is lowered.
Description
Technical field
the utility model relates to the metal enclosed metering cabinet of a kind of armored withdraw type alternating-current switch.
Background technology
existing conventional metal enclosed metering cabinet of armouring alternating-current switch is fixed in cabinet 1 inside with voltage transformer 4, current transformer 6, high-tension fuse 5 this type main elements usually; As shown in Figure 1, inlet wire cable (omission) is set on cabinet 1 again said elements is connected.Shortcoming is that cabinet 1 inner space is narrow and small, for the inconvenient maintenance of each element.In addition because cabinet 1 is charged, isolate cabinet and cut off the electricity supply so need be provided with in prime, the personal safety when guaranteeing to keep in repair, and the introducing of isolation cabinet has increased equipment cost.
Summary of the invention
the utility model purpose is: a kind of maintenance and lower AC metal closed switch metering cabinet of armored withdraw type of cost be convenient to is provided.
The technical scheme of
the utility model is: the AC metal closed switch metering cabinet of a kind of armored withdraw type; Comprise cabinet; Said cabinet is provided with the inlet wire cable, it is characterized in that also comprising the handcart that can pass in and out cabinet, on the said handcart from top to bottom fixed order voltage transformer, high-tension fuse summation current transformer are arranged; Also be fixed with moving contact on the said handcart; Said moving contact is connected with current transformer, high-tension fuse and voltage transformer through lead successively, and said cabinet internal fixation has the fixed contact that cooperates with moving contact, and said inlet wire cable links to each other with fixed contact.
are further preferred, be provided with the handcart guide rail described in the utility model in the cabinet, and guide rail slide block or the track roller that cooperates with the handcart guide rail is installed on the said handcart.
only need handcart is pushed in the cabinet when the utility model is specifically worked, and make the electricity consumption loop of dynamic and static contact contact conducting voltage instrument transformer, high-tension fuse summation current transformer get final product.And when the utility model need detect maintenance, only need handcart is shifted out cabinet, dynamic and static contact is disengaged, can break off the electricity consumption loop, voltage transformer, high-tension fuse summation current transformer are changed and keeped in repair.
The utility model has the advantages that:
are the AC metal closed switch metering cabinet of this armored withdraw type that provides of the utility model 1.; Because voltage transformer, high-tension fuse summation current transformer are fixed on the handcart; Can handcart be pulled out in cabinet during maintenance; Need not be confined to narrow and small cabinet inner space, so make maintenance convenient more.
are the AC metal closed switch metering cabinet of this armored withdraw type that provides of the utility model 2., because voltage transformer, high-tension fuse summation current transformer are fixed on the handcart, handcart breaks away from promptly with cabinet and cuts off the power supply; So under the prerequisite that satisfies the power supply department safety requirements; The cabinet prime need not be provided with the isolation cabinet, so, is not increasing under the situation that cabinet is dark and cabinet is wide; Save one and isolated cabinet, reduced many production costs.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the structural representation of the traditional AC metal closed switch metering cabinet of armouring;
Fig. 2 is the AC metal closed switch metering cabinet of the utility model armored withdraw type (handcart insertion);
Fig. 3 is the AC metal closed switch metering cabinet of the utility model armored withdraw type (handcart shifts out);
Fig. 4 is the independent structural representation of handcart among Fig. 2.
wherein: 1, cabinet; 2, inlet wire cable; 3, handcart; 4, voltage transformer; 5, high-tension fuse; 6, current transformer; 7, moving contact; 8, fixed contact; 9, handcart guide rail; 10, track roller.
Embodiment
embodiment: combine Fig. 2, Fig. 3 and shown in Figure 4; The AC metal closed switch metering cabinet of this armored withdraw type that the utility model provides; It has set up handcart 3 in cabinet 1 inside; And be provided with handcart guide rail 9 in the cabinet 1, and said handcart 3 bottoms are equipped with the track roller 10 that cooperates with handcart guide rail 9.On the said handcart 3 from top to bottom fixed order voltage transformer 4, high-tension fuse 5 summation current transformers 6 are arranged; Also be fixed with moving contact 7 on the said handcart 3; Said moving contact 7 is connected with current transformer 6, high-tension fuse 5 and voltage transformer 4 through lead successively, and is specifically as shown in Figure 4.And said cabinet 1 bottom is provided with inlet wire cable 2, and said cabinet 1 internal fixation has the fixed contact 8 that cooperates with moving contact 7 simultaneously, and said inlet wire cable 2 links to each other with fixed contact 8.
only need handcart 3 is pushed in the cabinet 1 when the utility model is specifically worked, and the electricity consumption loop that makes dynamic and static contact 7,8 contact conducting voltage instrument transformer 4, high-tension fuse 5 summation current transformers 6 gets final product.And when the utility model need detect maintenance, only need handcart 3 is shifted out cabinet 1, dynamic and static contact 7,8 is disengaged, can break off the electricity consumption loop, voltage transformer 4, high-tension fuse 5 summation current transformers 6 are changed and keeped in repair.
the foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is the content that lets people can understand the utility model and implements according to this, can not limit the protection range of the utility model with this.All equivalent transformation or modifications of doing according to the spirit of the utility model main technical schemes all should be encompassed within the protection range of the utility model.
