We wish your Christmas a warm, peaceful, happy reunion with your loved ones, and wish Christmas joy and joy in the New Year.

1. The degree of single-phase electric meter and three-phase electric meter

Whether the single-phase electric meter and the three-phase electric meter run in the same way should be divided into two situations. It must be determined whether the electric meter is equipped with a transformer. Then how to distinguish whether the three-phase electric meter has a transformer? Oh, if it is a small current, it is basically necessary to add a transformer, such as 1.5 (6) or 0.2 (1.3) A, etc., and a transformer with a relatively large current basically does not need to be added, such as 10 (60) A , 5(40)A and 30(100)A, etc. If the three-phase meter is not equipped with a transformer, the degrees of the single-phase meter and the three-phase meter are the same. If the three-phase meter is equipped with a transformer, the degree displayed by the three-phase meter must be multiplied by the multiple of the transformer Just work.

2. Maintenance and maintenance requirements for the meter box

1. According to the requirements, check whether the surface of the meter box is damaged, whether the box lock is intact, and whether there is any disorderly connection; all the electrical switches on the meter box should act lightly and reliably, without obvious noise, and the corresponding connection line knot and terminal should be There is no slack or disconnection.

2. When the fuse is to be replaced, the blown current should match the current of this loop.

3. There are voltages of various natures on the control box. The circuit must be clearly distinguished during warranty maintenance to avoid short circuit events.

4. When cutting off the power, immediately check whether the frame of the control cabinet has reliable grounding, and make the grounding resistance less than 4Ω.

5. Use a brush or a hair dryer to clean the screen board plug-in and the dust of each electromagnetic switch part, and check the state and connection of the electrical switch contacts in the control box, the insulation of the coil appearance and the movement of the mechanical parts are reliable.

6. Clean the dust inside and outside the meter box on time to ensure that the box is clean, safe to use, and the meter reading is clear.

7. Check that the meter, switch, and wire are not damaged or heated. Check whether the wire connector seat is loose or oxidized. Check whether the meter label is complete and whether there is damage.
