The different waveforms of transient recovery voltage (TRV) causing by earthing faults near a circuit breaker terminal are studied. The TRV characteristics of 500 kV circuit breakers in Northern China Power System Grid are summarized for 10% and 30%, and possibly 60%, of the interrupting rating short circuit capacities.It has been proved, that the TRV may exceed the 1EC Standard under certain operational conditions, and during the first few MS after rhe current interrupted, when the interrupting short circuit...

The different waveforms of transient recovery voltage (TRV) causing by earthing faults near a circuit breaker terminal are studied. The TRV characteristics of 500 kV circuit breakers in Northern China Power System Grid are summarized for 10% and 30%, and possibly 60%, of the interrupting rating short circuit capacities.It has been proved, that the TRV may exceed the 1EC Standard under certain operational conditions, and during the first few MS after rhe current interrupted, when the interrupting short circuit capacity is comparatively great. The initial transient recovery voltage (1TRV) will be obviously influenced by the high voltage apparatus of the carrier wave communication.

本文研究断路器端部故障时瞬态恢复电压(TRV)波形的变化情况。总结了华北电网500kV断路器在10%、30%断流容量情况下的恢复电压特性,井研究了可能出现的60%断流容量下的恢复电压特性。研究结果表明:在某些运行方式下,500kV断路器恢复电压会超过IEC标准;在断流容量比较大的情况下,在电流断开的几个μs内,电力载波装置对起始TRV波形产生很大的影响。

ABSTRACT

利用连续流量计与压差式密度计可以获得满意的产液剖面资料。但是,在垂直管柱中,由于滑脱等因素的影响,油水两相流动的流态变化十分复杂,因此连续测井资料的解释十分困难。为了解决这一问题,利用模型井研究了在不同含水率条件下涡轮转速与持水率之间的关系、视速度与平均流速之比同持水率之间的关系,以及在连续测量和点测两种条件下涡轮转速同平均流速之间的关系。在此基础上编制了四个关系图板和计算机解释程序。利用PC—1500计算机进行解释,可以给出各测点视速度回归图、分层产水量和产油量,绘出产油、产水剖面图。已测的20口井资料表明,研究成功的方法,灵敏度高,能发现低产层并给出定量解释结果,可对厚油层进行层内解释,与周围注水井吸水剖面结合,可给出注采关系图。在垂直管柱中,一定条件下,油泡向上运动时,为了补偿油泡的空缺,一部分重相向下流动,造成涡轮倒转。在这种情况下,利用所研究的方法也可以进行定量解释。

In this review article the most important task in the researches on cementing is discussed in the light of the newest achievements in oil well drilling. It is concluded that close attention must be paied to the protection of production capacity in cementing oil wells. This is illustrated by comprehensive descriptions of the evolutions of Specification for Materials and Testing for Oil Well Cement and the mechanism of sllurry contamination of producing formations. Besides, a practical instance is given to show the economic benefits resulted from strict control of water losses of slurries in cementing. Some commeats are put forward about the development and utilization-of water loss controlling additives in our country. Some new chemicals and instruments abroad are also introduced.
