Automatic packaging equipment high pressure measurement items

Automatic packaging equipment high pressure measurement items

Now take a look at the high pressure measurement of automatic packaging equipment. Today's automatic packaging equipment, many people also known as the bag type automatic packaging machine, the function of vacuum and only sealing the sub.

Before understand automatic packaging equipment of high voltage test, get to know the current transformer, current meter and other wiring and v. measuring instrument, need to disconnect high-voltage circuit, this circuit is connected equipment and instruments shall be all オ after power cut, even read current back to the cross-sectional area of the route to meet the requirements of the measured current value. 1) voltage transformer, the pressure gauge and other measuring instrument wiring and v, without a new high voltage circuit, can be charged homework, besides should abide by the relevant charged operation requirements, wire don't have a head, should try to short the length of the wire, wire connection with components to be solid, if necessary, it should be for conductor insulation bracket to be fixed.

The measurement of the high voltage measurement items of the automatic packaging equipment shall be carried out on the low voltage side of the transformer.

When measuring the high-voltage governing items of automatic packaging equipment and using the voltage transformer, all the wiring on the low-voltage side should be connected and checked correctly before connecting the wires on the high-voltage side with insulation tools. When operating, someone should protect the operator hand food and goggles on the platform. Outdoor operation must wear green batch.

Automatic packaging of high voltage test equipment, instruments and meters outside 売 is non-metallic, should with insulation: is the metal should be home ground: the location of it.

Fence ropes should be set around the high pressure measurement of automatic packaging equipment.

Provisions for the use of needle ammeter in high voltage measurement items of automatic packaging equipment:

1) It is prohibited to use wires to make measurements from the needle ammeter connected to the meter;

2) When measuring the current of each phase of the high-voltage cable, the distance between the lead wires of the cable head should be over 300m, and the insulation should be good. When there is a junction, it is strictly prohibited to measure.

3) When measuring a wire, pay attention to the distance to the ground and the distance between wires, and wear insulating gloves and boots.

4) Measuring range shall not be changed during measurement.

5) The ammeter should be wiped clean before use.

For high voltage measurement items of automatic packaging equipment, the provisions of using insulation resistance tester for measurement are as follows:

1) When measuring on the high-voltage equipment, two persons should make the measurement and fill in the team work ticket. The equipment and line under test should first cut off power, check electricity and discharge, and then measure.

2) Ensure that no one is on the equipment and line before measurement; When measuring cables and lines, inform the staff at the other end in advance. Do not allow non-staff to approach during measurement.

3) When several loops are mounted on the same rod, the measurement of any loop shall cut off the other loops to prevent induced voltage.

I hope the above information is helpful to you.
