Abstract

The utility model discloses a low-voltage draw-out type switch cabinet comprising a cabinet body, wherein an inner part of the cabinet body is separated into a front part and a back part by a separator plate; a top of the cabinet body is a horizontal bus-bar room, a plurality of function unit drawers are arranged in order in the cabinet body under the horizontal bus-bar room and in the front part of the cabinet body, branch buses and binding post parts of external cables are arranged in the back part of the cabinet body; the separator plate is a transparent polycarbonate separator plate; a bottom of the cabinet body is provided with cable inlet holes and cable outlet holes; and the cabinet body is assembled by section bars through screws. According to the low-voltage draw-out type switch cabinet of the utility model, the inner part of the cabinet body is separated into the front part and the back part through the separator plate, when a fault occurs in any one area, the other part can not be affected, thus the low-voltage draw-out type switch cabinet can be used safely; the low-voltage draw-out type switch cabinet is assembled by the section bars through the screws, thus the low-voltage draw-out type switch cabinet can be assembled flexibly, and may have a high mechanical strength and a reliable insulation protection; and the low-voltage draw-out type switch cabinet also has the advantages of high universality, compact structure, safety and reliability.

Description

Low pressure draw out switchgear cabinet

Technical field

The utility model relates to a kind of low pressure draw out switchgear cabinet; Be mainly used in electric energy conversion, distribution and the control of distribution system power, distribution and the motor control center of industries such as power plant, chemical industry, metallurgy, weaving, skyscraper, belong to power equipment and make the field.

Background technology

Low pressure draw out switchgear at home and abroad application surface is very wide, and amount is also very big.Its drawer technology is the key of decision draw out switchgear cabinet performance.At present, the draw out switchgear cabinet drawer of being produced generally adopts card edge type mechanism, and whole drawer receives the very mechanical impact force of hard intensity when inserting, and drawer itself and components and parts are caused the problem of becoming flexible slippage easily.

Existing low pressure draw out switchgear cabinet; Dividing with arrangement of cabinet functional unit is unreasonable; Not only maintenance difficulty, and lack enough safety guarantee and safety measure, both be unfavorable for the safe operation of equipment and maintenance fast; Also can't realize the quick assembling and the debugging of equipment, and shortage or operability.

In addition; Level, the vertical bus of the low pressure draw out switchgear cabinet that uses at present are connected more unreasonable with the functional unit drawer; Be prone to cause loose contact and generate heat; The outside naked shell protection of bus-bar system can't be selected assembling arbitrarily for use according to user's request simultaneously, make low-tension switch cabinet poor expandability, also take up space simultaneously, its fail safe is not high yet.

Summary of the invention

In order to overcome above-mentioned deficiency, the utility model purpose is to provide a kind of performance safe and reliable, convenient assembling fast, is convenient to the low pressure draw out switchgear cabinet that connects up and overhaul.

To achieve these goals, the technical scheme of the utility model employing is:

Low pressure draw out switchgear cabinet; It comprises cabinet; Cabinet inside is separated into forward and backward two parts by dividing plate, and the top of cabinet is the horizontal bus chamber, and a plurality of functional unit drawers are positioned at the cabinet of below, horizontal bus chamber successively; And be positioned at the forward part of cabinet, the rear portion of cabinet is divided into the binding post portion of branch bar and external cable; Said dividing plate is the clear polycarbonate dividing plate.

The bottom of said cabinet is provided with long cable section of ingoing line hole and cable outlet hole.

Said cabinet is to be assembled through screw by section bar.

The beneficial effect of the utility model: because cabinet inside is separated into forward and backward two-part design by dividing plate, when break down in any one zone, all the other compartments all do not influence, and use safer; Switch cabinet body is assembled with bolt by section bar, does like this to make assembling flexibly, and its mechanical strength is high simultaneously, also has reliable insulation protection; The utility model also has highly versatile, compact conformation, safe and reliable characteristics.

Description of drawings

Below in conjunction with accompanying drawing the utility model is done further to specify.

Fig. 1 is the structural representation of the utility model;

Fig. 2 is a side-looking structural representation shown in Figure 1.

Among the figure: 1, cabinet; 2, functional unit drawer; 3, horizontal bus chamber; 4, dividing plate; 5, dividing plate; 6, outside side plate; 7, long cable section of ingoing line hole; 8, cable outlet hole; 9, the rear section of cabinet.

Embodiment

Like Fig. 1, shown in 2; Low pressure draw out switchgear cabinet, it comprises cabinet 1, cabinet 1 inside is separated into forward and backward two parts by dividing plate 4; The product top of cabinet l is horizontal bus chamber 3; A plurality of functional unit drawers 2 are positioned at the cabinet of 3 belows, horizontal bus chamber successively, and are positioned at the forward part of cabinet l, and the rear section 9 of cabinet is the binding post portion of branch bar and external cable.Switch cabinet body is assembled with bolt by section bar, and outside side plate 6 static electrifications dust, and makes it have reliable insulation protection function.Cabinet 1 is divided into the cell that horizontal bus chamber 3, vertical bus chamber 4 etc. isolate each other; Cabinet is separated into forward and backward two parts by dividing plate 5; Functional unit drawer 2 is positioned at the front portion and is installed in the cell that is divided into by supporting plate, and the indoor guide rail that is equipped with just can make drawer in the indoor slip of functional unit.The extraction of functional unit drawer 2 and be inserted as lever; Cooperate the loop below the electric current 200A to use; The plug-in unit that the power supply turnover of main circuit is 200A by two rated current is respectively accomplished, and secondary circuit adopts the slidingtype plug connector to connect, and drawer and main switch are mechanical interlocking; Can link to each other with computer through interface function unit drawer, use to do remote detection control.The bottom of said cabinet 1 is provided with long cable section of ingoing line hole 7 and cable outlet hole 8.

Operation principle: the functional unit of different cabinets is connected on the line of horizontal bus chamber; The functional unit of same cabinet is connected in parallel on the design on the vertical bus; Make same or each functional unit drawer is pegged graft more tight; Contact is good, makes big electric current also can increase the fail safe of equipment through can therefore not generating heat; Cabinet inside is separated into forward and backward two-part design by dividing plate, and when break down in any one zone, all the other compartments all do not influence, and uses safer; Switch cabinet body is assembled with bolt by section bar, does like this to make assembling flexibly, and its mechanical strength is high simultaneously, also has reliable insulation protection; Said bus is to be formed through the Polycarbonate plastics shell seal by copper busbar, thereby its mechanical strength is increased, and thermal diffusivity is better, satisfies different user's requests; The extraction of functional unit drawer and insert control unit and constitute by propulsive mechanism, interlocking device, spacing etc., when drawer was in link position major loop switch connection power supply, door was not opened, and drawer can not be extracted out; On the contrary, if switch is not at the disjunction state, drawer can not insert.In order to ensure safety, the maintainer can use padlock that switch lock is stayed in the separating brake position.

The above is the preferred implementation of the utility model, can not limit the interest field of the utility model certainly with this.Should be pointed out that for those skilled in the art, the technical scheme of the utility model is made amendment or is equal to replacement, do not break away from the protection range of the utility model.
