电气英文自我评价范文电气英文自我评价范文篇一My name is *, engaged in electrical equipment repair work has been 5 years. Since * * * years to * * company, has been working for more than two years. From entering the company has been engaged in substation operation and maintenance and management. Has participated in and organized a high-pressure measurement and relay protection setting and calibration; reactive power compensation and voltage setting; DC screen inspection and maintenance; substation secondary circuit fault and processing; high-voltage cabinet failure and treatment; high-voltage cable head Production and processing; substation in the spring and autumn all overhaul and maintenance; outdoor high voltage overhead line fault handling and maintenance. I always assiduously with high-voltage technology to improve the operating rate of the combination, and actively study the principles of high-voltage equipment and maintenance experience, and insist on constantly improve their theoretical and practical skills to solve the substation running a lot Technical problems, in order to improve the power transmission and transmission equipment operating rate and laid a good foundation. Substation is the power system in the power of the voltage and current transformation, concentration and distribution of the place. In order to ensure the quality of electrical energy and the safety of the equipment, voltage regulation, power flow and voltage distribution, distribution of power, current and power in each node and branch of the power system and control of transmission and distribution lines and Protection of major electrical equipment. Now substation over the past two years have experienced the work summarized as follows:1, vacuum circuit breakers in the daily operation of the fault types and treatment.November 8, 2018 due to power company line fault on my company large power outage for 3 hours. After receiving the notice, we press the power substation regular power outage procedures for power outages. When the power company to deal with failure after transmission, according to power transmission step. Then found the 35KV main transformer vacuum circuit breaker refused to close, this is my company has just put into operation for two months the first time the substation problems, our company substation 35KV high voltage cabinet vacuum circuit breaker is applied Chint ZN85-40.5 circuit breakers. In the experimental state found after closing the circuit breaker command, closing electromagnet action, the core plunger will close the pawl top open, closing the spring release energy, driving the circuit breaker closing, but the circuit breaker interrupter can not be together brake. After analysis, indicating that mechanical failure has been excluded, indicating that the secondary line fault, found in the secondary auxiliary plug has a needle and control wire desoldering, vacuum breaker to deal with after closing, fault problem solving. Vacuum circuit breakers in the daily work of the most prone to failure to be summed up: 1. Positive air circuit breaker refused to sub (gate)2. Vacuum circuit breaker body energy storage, energy storage motor stop 3. Vacuum interrupter interrupter can not be disconnected 2, the current transformer secondary open and deal with* * The end of the month, the power company came in February of the electricity details, with my company substation measured by the amount of difference 20182KW.h. I led the technical staff to conduct a comprehensive inspection of high-pressure measurement, due to limited conditions, failed to find fault problems. The company invited the power company metering and testing center substation secondary circuit test. The current transformer, voltage transformer, secondary voltage drop and secondary load, electric energy meter of 35KV and 10KV each switch cabinet are tested. In the power company equipment testing found 35KV high back-up protection of the terminal has an indirect open phenomenon. After processing, in the specified time with the power company metering center, the problem has been resolved. Current transformer CT primary winding number of turns is small, the use of a winding in series in the measured line, the secondary winding turns, and measuring instruments and relays and other current coil in series, measuring instruments and relays and other current coil impedance is very small , So the normal operation of CT is close to short-circuit state. CT secondary current size determined by the primary current, secondary current generated by the magnetic potential, is to balance the current magnetic potential. If the secondary open circuit, the impedance is infinite, the secondary current is equal to zero, the magnetic potential is equal to zero, can not balance the current generated by a magnetic potential, then a current will act on the excitation, the core serious saturation. Magnetic saturation increases the iron loss, CT
