Get started first, follow the master to see more and do more, ask the master more, ask if you don't understand, start with the simple motor control circuit, be familiar with the schematic diagram, unfold the diagram, install the wiring diagram, and then look at the circuit protection diagram. Starting from actual combat, you will gradually learn, master the technology and accumulate experience, and then do it yourself. Of course, there is no shortage of theory, and the school will make up for it in combination with reality.

With a certain foundation, all the drawings on the site should be roughly recorded, the instructions should be read several times, and the national technical standards and countermeasures should be grasped in time. After that, you should actively participate in technical transformation, plan and prepare measures, and modify drawing procedures. Slowly, you will become a technician, and then learn some management knowledge and team management system, and you will become a team leader.

Master the knowledge are:

: (1) The working principle and application of relay protection, automatic device and electric measuring instrument for high voltage users.

(2) Relevant regulations on handover and preventive test of electrical equipment for high-voltage users, as well as relay protection and automatic setting.

(3) Basic requirements of automatic switching device for standby power supply.

(4) At present, the commonly used methods for checking the vacuum degree of high-voltage vacuum circuit breakers should be replaced under any circumstances.

(5) Knowledge of equipment insulation and measuring DC resistance.

(6) Understand the schematic diagram of DC operation inverse time overcurrent protection.

(seven) the nature of the load of high-voltage user service, the key parts of electricity use, and the conditions and scope of safe electricity use.

(8) The basic methods to adjust the load to save electricity, improve the power factor and improve the safety level of electricity use.
