lead type transformerMust grounding protection be selected for the lead?
1、lead type transformerThe lead wire of the transformer cannot be grounded immediately. For the general transformer used by everyone, TN power supply and distribution system is selected. The neutral wire of the lead transformer is grounded immediately. If the phase wire is grounded again, there will be a two-connected ground short circuit fault. This short circuit capacity is very large, which will damage the machinery and equipment, very much the power transmission line. Therefore, the protection equipment will quickly jump power, protect the common fault points and power supply and distribution system;
2, so that the system software can all operate normally,lead type transformerThe neutral line of the transformer is to be grounded immediately, which is protective grounding. The neutral line of the lead-type transformer is led out according to the waterproof casing on the transformer, which is connected with the lead-type transformer casing through the transmission line, and then the grounding device;
3. In order to operate the safety of the staff and other staff close to the lead transformer,lead type transformerThe casing should have a reliable grounding device;
4. The casing of the power consumption machine equipment is to be grounded, but the grounding device method is different.
5. There is also a kind of system software, TT power supply and distribution system. This kind of system software is less used, that is, grounding body is set around the power consumption machine equipment, and the casing of the power consumption machine equipment is immediately connected with this grounding body to act as an on-the-spot grounding device.
lead type transformerInternal main maintenance is divided into two types: 1. Electricity consumption maintenance, collecting the internal electricity consumption change of the main transformer to distinguish; 2. Non-electricity consumption maintenance, such as heavy coalbed methane maintenance, on-load transformer transformer also has on-load coalbed methane maintenance, which collects the internal vapor transformation of the transformer to distinguish.
