Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It is noted that the aspects described below in connection with the figures and the specific embodiments are only exemplary and should not be understood as imposing any limitation on the scope of the present invention.
As shown in fig. 1 and 2, the utility model discloses an anti-electromagnetic interference's automatically controlled cabinet, including the cabinet body 101, be provided with first installing zone 201 and second installing zone 202 in the cabinet body 101, the opening orientation of first installing zone 201 is opposite with the opening orientation of second installing zone 202 for components and parts in first installing zone 201 and the components and parts in the second installing zone 202 are installed on two relative panels of the cabinet body 101, and the distance has reached the farthest. A metal partition plate 203 for shielding electromagnetic interference is disposed between the first mounting area 201 and the second mounting area 202, and the metal partition plate 203 is preferably a galvanized plate that is not painted. At least one transverse wiring pipeline 204 and at least one vertical wiring pipeline 205 are arranged on the metal partition plate 203, and the transverse wiring pipeline 204 and the vertical wiring pipeline 205 are arranged to facilitate laying and shaping of wires inside the electric control cabinet and simultaneously connect components in the first installation area 201 and the second installation area 202.
The first cabinet door 102 is disposed on the first mounting area 201, and the second cabinet door 206 is disposed on the second mounting area 202. In a possible embodiment, a display screen, an emergency stop button and a status display lamp are arranged on the first cabinet door 102. The first cabinet door 102 and the second cabinet door 206 are both provided with heat dissipation fans.
In this embodiment, the first mounting area 201 is disposed at a side of the second mounting area 202, the first mounting area 201 is a PLC mounting area, and the second mounting area 202 is a frequency converter or servo controller mounting area. To the device that has certain electromagnetic interference such as converter, servo controller among the automatically controlled cabinet, through leaning on automatically controlled cabinet left and right both sides installation, can be convenient for this type of device ground connection to handle, shorten the length of earth connection, reduce the harm of electromagnetic interference to other equipment.
In a possible embodiment, a power supply mounting area 103 is provided at the top of the cabinet 101. Arranged in the power supply installation area 103 are a power supply and main and branch circuit power switches (currently, most air circuit breakers of various models are). So that the operation of power supply and cut-off, especially the operation of power failure and plate hanging is facilitated for the operating personnel.
In addition, in order to reduce the electromagnetic interference generated by wiring, a double-layer wiring terminal block 104 is arranged at the bottom of the cabinet body 101, an upper wiring terminal block 104a is used for laying control cables, and a lower wiring terminal block 104b is used for laying power cables. When the wiring terminal block is designed and arranged, the power lines such as the power line and the load line are installed in a layered mode with the auxiliary control signal line, and the installation position of the power line and the load line is higher than that of the auxiliary control signal line, so that electromagnetic interference between the two functional wires can be avoided, and measurement in the later overhauling process is facilitated.
In order to improve the electromagnetic interference from the grounding point of view, grounding copper strips (not shown in the figure) are disposed on two sides of the cabinet 101, and the cabinet 101, the first cabinet door 102 and the second cabinet door 206 are all connected to the grounding copper strips. The side of the cabinet body 101 is also provided with an incoming filter (not shown in the figure), the incoming filter is directly installed at the power input, attention needs to be paid to the fact that the metal galvanized shell of the filter is in good contact with the installation plate of the cabinet body, and the input line and the output line of the filter cannot be placed side by side.
The components arranged in the electric control cabinet mainly comprise a PLC, a touch screen, a servo, a frequency converter, a low-voltage electric appliance, an industrial control instrument and the like. In these products, each product has its own electromagnetic compatibility standard, so the electromagnetic compatibility requirements for each product in the industrial control system are different. For example, the driveline is relatively immune, but it is a major source of interference. However, for the meter, the interference signal generated by the meter is small, and the interference resistance of the meter is mainly considered in the system design. Therefore, in a possible embodiment, as shown in fig. 3, the first installation area 301 may be disposed above the second installation area 302, the first installation area 301 is a strong electric installation area, and in addition, in general, electronic industrial control devices (such as a PLC, a frequency converter, a switching power supply, electronic circuits with various functions, and the like) are installed on the upper portion of the electric control cabinet to avoid the influence of environmental temperature, humidity, dust, and the like, and therefore, may also be disposed in the first installation area 301. The second mounting region 302 is a weak current mounting region to reduce interference of strong current to weak current. When the electromagnetic contactor and the relay are driven by the PLC, the control device and the controlled device are arranged in a layered mode, and the controlled device is located below the PLC. The advantage of doing so is that the follow-up wiring construction of being convenient for, and overhaul the change.
To sum up, the utility model discloses a set up first installing zone and the second installing zone that the opening orientation is opposite for components and parts distance in first installing zone and the second installing zone is the farthest, avoids the emergence of coupling. Through set up at least one horizontal wiring pipeline and at least one vertical wiring pipeline on metal partition, can realize the wiring between first installing zone and the second installing zone, can ensure to avoid the electromagnetic interference between the long distance parallel distribution's the cable again.
