Abstract
The utility model provides a combined type medium voltage switch cabinet, which comprises a front cabinet and a back cabinet, wherein the back cabinet is of a frame structure and comprises a top cover, a bottom plate, a left column, a right column, a middle column, a left small side plate, a right small side plate, a back small side plate, a left side cross beam, a right side cross beam, a side plate of a bus bar chamber, a side plate of a cable chamber, a lower sealing plate of the bus bar chamber and a back sealing plate of the bus bar chamber, wherein the back cabinet is connected with the front cabinet through the left column, the right column and the middle column. The frame structure is adopted by the back cabinet, an integral type side plate is not needed, and right side plates of the bus bar chamber and the cable chamber are cancelled, so materials are saved, the processing is facilitated, and the labor intensity is simultaneously reduced; and a double-layer bending structure and a circular boss positioning and riveting structure are adopted by side surfaces of a cabinet body, bolted connection and a large-small hole mutual accommodation process are not needed, fastening pieces beyond the cabinet width does not exist on the two side surfaces of the switch cabinet, so the appearance is attractive and the cabinet can be conveniently mounted and spliced on the spot. According to the combined type medium voltage switch cabinet, different materials can be selected and used economically and reasonably according to the current magnitude of a system, the influences of magnetic hysteresis loss and eddy-current loss in the large-current system are avoided, the heating is reduced, and temperature rise is lowered.
Description
Technical field
The utility model relates to a kind of electrical control cabinet, particularly a kind of Medium Voltage Switchgear.
Background technology
The present Medium Voltage Switchgear that uses, cabinet is bigger, and in order to satisfy requirement of strength, the outer panel of cabinet generally all adopts whole plate structure, the material requirements height, difficulty of processing is big, and stock utilization is low.Use bolt etc. that outer panel is fixed on the switch cabinet, the switch cubicle two sides have securing member such as bolt to stretch out, and neither attractive in appearance, also inconvenient on-the-spot the installation pieced together cabinet.Material in the switch cubicle Circuits System is changed inconvenient, when electric current in the system changes, when particularly electric current is very big, may cause heating, temperature rising because of magnetic loss and eddy current loss.
The utility model content
The utility model aims to provide a kind of Medium Voltage Switchgear, reduces the specification requirement of material therefor, and economical with materials reduces manufacturing cost, and integral replacing is convenient, can solve the Medium Voltage Switchgear of big current system temperature rise economically.
The technical solution of the utility model is: a kind of composite type Medium Voltage Switchgear, cabinet and back cabinet before comprising, described back cabinet is a frame structure, comprise top cover, base plate, left and right sides central post, about shrouding and back shrouding under the little side plate in back, left and right sides crossbeam, bus-bar room side plate, cable vault's side plate, bus-bar room, described back cabinet is connected with preceding cabinet by left and right sides central post.
Described top cover, base plate, the little side plate of central post and back are double-deck bending structure.
Described side crossbeam is connected with rivet with the little side plate in back with central post, the bus-bar room side plate is connected with rivet with top cover, left central post, left back little side plate, left side crossbeam and base plate with cable vault's side plate, shrouding is connected with rivet with the little side plate in back behind the bus-bar room, under the bus-bar room behind shrouding and preceding cabinet and side crossbeam, the bus-bar room under shrouding and top cover and the bus-bar room shrouding be connected with bolt.
The utlity model has following advantage:
1. the back cabinet adopts tower structure, without the integral type side plate, has reduced the requirement to material specification, and has cancelled bus-bar room and cable vault's right plate, has saved material, simultaneously part is broken the whole up into parts, and both convenient processing has alleviated labour intensity simultaneously again.
2. double-deck bending structure and the riveted joint of boss platform location are adopted in the cabinet side, and the technology without bolt connects and big aperture is given in to each other makes the switch cubicle two sides all not exceed the wide securing member of cabinet, and be not only attractive in appearance but also make things convenient for on-the-spot the installation to piece together cabinet.Primary and necessary condition have been created for realizing the middle cabinet integral replacing in the switch cubicle system.
3. the back cabinet adopts frame structure, and is more flexible with material, can be according to the different materials of selecting for use of system power size economical rationality, solve the influence of magnetic hysteresis loss and eddy current loss in the big current system, and reduce heating, reduce temperature rise.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the double-deck bending riveted structure of a utility model schematic diagram.
Fig. 3 is the utility model boss location riveted structure schematic diagram.
Among the figure: cabinet before the 1-, 2-top cover, 3-base plate, 4-rivet, cabinet behind the 5-, 6-central post, little side plate behind the 7-, 8-side crossbeam, 9-bus-bar room side plate, 10-cable vault side plate, shrouding under the 11-bus-bar room, shrouding behind the 12-bus-bar room, 13-bolt.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, cabinet 1 and back cabinet 5 before the utility model composite type Medium Voltage Switchgear comprises.Back cabinet 5 adopts frame structure, comprise top cover 2, base plate 3, the left and right sides central post 6 that links to each other with preceding cabinet 1, about shrouding 11 and back shrouding 12 etc. under the little side plate 7 in back, left and right sides crossbeam 8, bus-bar room side plate 9, cable vault's side plate 10, bus-bar room, wherein the little side plate 7 in top cover 2, base plate 3, central post 6 and back adopts double-deck bending structure.Side crossbeam 8 adopts high strength rivet 4 and little side plate 7 riveted joints of central post 6 and back; Bus-bar room side plate 9 and cable vault's side plate 10 and top cover 2, left central post 6, left back little side plate 7, left side crossbeam 8 and base plate 3 riveted joints.Back cabinet adopts tower structure, without the integral type side plate, and has cancelled bus-bar room and cable vault's right plate, has saved material, simultaneously part is broken the whole up into parts, and has reduced the specification requirement to material, can reduce manufacturing cost.Because double-deck bending structure and boss location riveted structure is adopted in the cabinet side, the cabinet side does not all have and exceeds the wide securing member of cabinet.Shrouding 11 adopts bolt 13 to be connected with preceding cabinet 1 and side crossbeam 8 under back cabinet 5 bus-bar rooms; Shrouding 12 is riveted with the little side plate 7 in back behind the bus-bar room, and is connected with shrouding 11 employing bolts 13 under the bus-bar room with top cover 2.
