Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in Figure 1 and Figure 2, the present invention is front and back enabling form, and according to electrical primary system schema, the major electrical equipment element of low voltage switchgear adopts top-down arrangement.Electric elements mainly comprise: main busbar 10, isolating switch 8, current transformer 6, breaker of plastic casing 4, branch's busbar 5.After the low voltage switchgear spelling cabinet of different schemes, main busbar 10 is the transmission part of principal current.The electric elements of switchgear inside form connection of circuit by branch's busbar 5.
Current transformer 6, breaker of plastic casing 4 are all installed on horizontal mounting rail 3.Horizontal mounting rail 3 is connected on perpendicular mounting rail 2 by securing member 11.Perpendicular mounting rail 2 links together with side plate 17, curb girder 12.
Perpendicular mounting rail 2 arranges installation through hole by 20mm spacing, and horizontal mounting rail 3 can freely adjust according to actual needs in perpendicular mounting rail 2 short transverse.
The both sides of tank bracket 1 arrange side plate 17, curb girder 12 respectively, and side plate 17, curb girder 12 arrange digital and analog hole with 25mm spacing.According to installation needs, determine that perpendicular mounting rail 2 is behind position, cabinet depth direction, directly on digital and analog hole, advance tapping fastening fast tapping screw with pneumatic tool, perpendicular mounting rail is closely fixed on side plate, curb girder.
Isolating switch 8 is arranged on isolating switch mounting rail 7, and isolating switch mounting rail 7 adopts the processing technology of double bending to be shaped, as shown in Figure 4.
Isolating switch 8 to be undertaken point by isolator operating mechanism 13, closing operation.Operating mechanism support 14 supports isolator operating mechanism 13, makes isolator operating mechanism 13 can adopt the mode of operation of cabinet inner rotary.Operating grip is extended type, reaches laborsaving object.During operation, cabinet door is closed, and fully ensures personal security.
Tank bracket 1 of the present invention is C assembled structure, C arranges digital and analog hole 18 by 25mm spacing, element mount can find digital and analog hole 18 in pairs in length three directions of tank bracket 1, this design can according to different needs, the position of flexible adjustment installed part, the aperture of digital and analog hole is ∮ 5.2, directly by tapping screw tapping on digital and analog hole during installation, reaches the effect of quick assembling.
The top, left and right side of tank bracket 1 does not arrange C part, is stuck between the C of front and back, plays a supportive role by after top cover 15 bending, distortion when avoiding tank bracket 1 to lift by crane.When carrying out main busbar 10 and installing, top cover 15 can be removed, main busbar 10 can unhinderedly be installed to main bus bar folder 9 from top, bus clip 9 is fixed on bus clip mounting rail 16, bus clip 9 suitably can move adjustment, is on same straight line to make the main busbar 10 of the low voltage switchgear of spelling cabinet.
Tank bracket 1 adopts side to arrange closed side plate 17, and opposite side only arranges the unenclosed construction of curb girder 12, and after spelling cabinet, side plate 17 and adjacent cabinet are formed to be separated, and reaches and both ensures equipment protection grade, reduce again the object of material consumption.
Side plate 17 front portion arranges digital and analog hole 18, and can pass through tapping screw mounting terminal support plate 19, secondary terminals 20, digital and analog hole 18 can adapt to different electrical arrangement, the quantity of flexible adjustment terminal support plate 19, secondary terminals 20 and position.
Portion arranges earthing bar 22, zero-emission 23 under the invention, and as shown in Figure 3, earthing bar 22, zero-emission 23 adopt arranged superposed, and to save wiring space, earthing bar 22 is fixed near tank bracket 1, is fixed with insulator 21 at earthing bar 22 two ends; Zero-emission 23 is supported on earthing bar 22 by insulator 21 overlap; Earthing bar 22, zero-emission 23 arrange some modularization wiring holes, is convenient to outgoing lines cable and connects.
The present invention arranges dismountable base plate 25 in the bottom of tank bracket 1, base plate 25 offers corresponding circular hole, can clamping turriform sealing ring 24, during installation, turriform sealing ring 24 cuts out the hole of corresponding size according to cable specification, cable can pass through turriform sealing ring 24, and turriform sealing ring 24 blocks again the gap that cable passes simultaneously, and low voltage switchgear can be avoided like this to be subject to cable trough moisture and toy intrusion.
Certainly; the present invention also can have other various embodiments; when not deviating from the present invention's spirit and essence thereof; those of ordinary skill in the art can make various corresponding change and distortion according to the present invention, but these change accordingly and are out of shape the protection range that all should belong to the claim appended by the present invention.
