Due to its special custom nature, non-standard measuring cabinets have a series of special requirements for internal wiring.
First of all, the rationality of the wiring is crucial. According to the layout and connection requirements of the equipment in the cabinet, a clear and concise line direction should be planned to avoid line crossing and entanglement to reduce electromagnetic interference and signal loss. At the same time, sufficient space and channels should be reserved for subsequent equipment maintenance and upgrades.
For the selection of cables, it is necessary to select cables of appropriate specifications and materials according to factors such as current size, voltage level and working environment. For example, for high current loops, wires with a large enough cross-sectional area should be selected to ensure load-bearing capacity and reduce heat generation.
During the wiring process, the cables must be firmly and reliably fixed. Avoid loosening or falling of cables due to vibration or external force, which may affect the normal operation of the equipment. Special fixing devices such as wire clamps and wire troughs can be used.
Special requirements also include good grounding and shielding measures. Grounding must comply with relevant standards to ensure the safety of equipment and personnel, while effectively suppressing electromagnetic interference. For sensitive signal lines, shielded cables should be used, and the shielding layer should be well grounded to improve the stability and accuracy of signal transmission.
The identification and marking of cables should not be neglected. Clear and accurate identification helps to quickly identify the function and direction of the line, which is convenient for troubleshooting and maintenance.
In addition, the wiring should also consider fire resistance and flame retardancy. Select cables and materials that meet fire protection standards to reduce the risk of fire. For example, in some places with high requirements for electromagnetic compatibility, the wiring of Non-standard measuring cabinet needs to more strictly control the distance and direction between lines to prevent electromagnetic interference from affecting the measurement accuracy.
In short, the wiring method inside the Non-standard measuring cabinet needs to take into account a variety of factors, follow the relevant electrical specifications and standards, and achieve reasonable planning, correct selection, firm fixing, good grounding and shielding, clear identification and fire resistance. Only by meeting these special requirements can the safe and reliable operation and accurate measurement function of the Non-standard measuring cabinet be guaranteed.
