Abstract
The utility model discloses a kind of low-tension switch cabinet internal components arrangement, it comprises general supply region (1), alternating-current electric element area (2), PLC region (3) and detecting element inlet wire region (4), it is characterized in that: general supply region (1) is positioned at the upper left side of switch cubicle, the lower left of alternating-current electric element area (2), PLC region (3) is positioned at the upper right side of switch cubicle, detecting element inlet wire region (4) is positioned at switch cubicle lower right, four described regions keep apart respectively by horizontal wire casing (5) and vertical wire casing (6), solve when to cause PLC to receive the signal input of Site Detection element because device layout in existing low-tension switch cabinet is unreasonable and signal transacting time, because strong electromagnetic causes the inaccurate poor reliability of signal, often can there is misoperation and affect the problems such as the normal use of equipment.
Description
Technical field
The utility model belongs to low-tension switch cabinet device separation, particularly relates to a kind of low-tension switch cabinet internal components arrangement.
Background technology
Low-tension switch cabinet is that electrically one of control cubicle is commonly used at scene, total power switch is furnished with in low-tension switch cabinet, A.C. contactor, frequency converter, the signal input line etc. of PLC and Site Detection element, owing to there being forceful electric power source in cabinet, the device that the electromagnetic interference such as frequency converter and A.C. contactor is strong, A.C. contactor closes in disconnection can produce large electromagnetic interference instantaneously, frequency converter ability is exactly a large electromagnetic interference source, when often causing PLC to receive the signal input of Site Detection element because layout is unreasonable and signal transacting time, because electromagnetic interference causes the inaccurate poor reliability of signal, often can there is the normal use that misoperation affects equipment.
Summary of the invention
The technical problems to be solved in the utility model: a kind of low-tension switch cabinet internal components arrangement is provided; when to cause PLC to receive the signal input of Site Detection element because device layout in present low-tension switch cabinet is unreasonable to solve and signal transacting time; because strong electromagnetic causes the inaccurate poor reliability of signal, often can there is misoperation and affect the problems such as the normal use of equipment.
Technical solutions of the utility model:
A kind of low-tension switch cabinet internal components arrangement, it comprises general supply region, alternating-current electric element area, PLC region and detecting element inlet wire region, general supply region is positioned at the upper left side of switch cubicle, the lower left of alternating-current electric element area, PLC region is positioned at the upper right side of switch cubicle, detecting element inlet wire region is positioned at switch cubicle lower right, and four described regions keep apart respectively by horizontal wire casing and vertical wire casing.
Insulation cover plate is had above electric component in general supply region.
Connection conductor arrangement between four described region devices is in horizontal wire casing and vertical wire casing.
The beneficial effects of the utility model:
Device in low-tension switch cabinet is divided into four large regions according to strong and weak electricity by the utility model; wire casing is adopted to keep apart between regional; structure is simple; rationally distributed; forceful electric power electromagnetic interference influence weak electric signal can be prevented; the normal operation of interference PLC; solve when to cause PLC to receive the signal input of Site Detection element because device layout in existing low-tension switch cabinet is unreasonable and signal transacting time; because strong electromagnetic causes the inaccurate poor reliability of signal, often can there is misoperation and affect the problems such as the normal use of equipment.
accompanying drawing illustrates:
Fig. 1 is that the utility model low-tension switch cabinet internal components is arranged and isolation schematic diagram.
embodiment:
A kind of low-tension switch cabinet internal components arrangement, it comprises general supply region 1, alternating-current electric element area 2, PLC region 3 and detecting element inlet wire region 4, general supply region 1 is positioned at the upper left side of switch cubicle, the lower left of alternating-current electric element area 2, PLC region 3 is positioned at the upper right side of switch cubicle, detecting element inlet wire region 4 is positioned at switch cubicle lower right, four described regions keep apart respectively by horizontal wire casing 5 and vertical wire casing 6, mains switch is installed in general supply region 1, bus bar etc., in alternating-current electric element area 2, the devices such as frequency converter A.C. contactor are installed, PLC is installed in PLC control area 3, mainly binding post is installed in detecting element inlet wire region 4, be used for connecting vulnerabilities scan signal, as checked element input signal, the output signal etc. of PLC, general supply region 1, alternating-current electric element area 2, be connected to each other by wire between PLC region 3 and detecting element inlet wire region 4.
Device classification subregion in cabinet is installed by the utility model, and avoid electromagnetic interference as far as possible, isolated between regional by wire casing, isolate interference further, wire casing can adopt metal raceway or plastic wire groove.
Owing to being provided with forceful electric power wiring bus bar in general supply region 1, bus bar is all-metal, usually be connected with and exchange 380V voltage, during in order to prevent staff when opening cupboard or overhaul, collisionless is to generation electric shock accidents, above the electric component in general supply region 1, have insulation cover plate.
Conductor arrangement between four described region devices is in horizontal wire casing 5 and vertical wire casing 6, and wiring completes slot cover plate on bonnet, makes whole switch cubicle neat and artistic.
Claims (3)
