3 Txuas cov xov hlau rau kev txij nkawm 3 {. 1}} Cov xov hlau tsis kam ntawm ob qho kawg ntawm cov hlau, siv cov tawv ntoo zoo kom huv Nws, luv luv-Circuit Co, thiab lwm qhov kawg yog ntsuas nrog cov tshuaj ntau × 1 iav. Tus nqi tiv-yuav tsum yog<10Ω, and the variation range should not exceed 1Ω, otherwise the wire may exist. Joints that are not found or unchecked should be inspected. 3.3 Use the multimeter resistance × 1 gear in the control room to measure the resistance between the three wires from the field. The resistance between the common short wires should be <10Ω, and the variation range should not exceed 1Ω; measure the common short wire and the third wire respectively. The resistance between the resistors should be similar and the difference should not exceed 1Ω. 3.4 Check that the connecting wire shield is intact, is effectively grounded, and is single-ended grounded (usually grounded in the control room). The resistance between the shield and the system ground bar should be <5Ω. 3.5 Check if the cable is aging and the skin is damaged.
