China News Service, Handan, May 2 (translated by Wang Tian and Kong Fanxia) "Look, this instrument that looks like a cat is the fourth-generation 'electric cat' - 'clamp-shaped palm quick-checking instrument', 'cat-eared instrument'. 'Connect the current line, 'cat tail' connect the voltage line, the 'cat' brain records the calibration error index..." On the morning of the 2nd, at the State Grid Hebei Electric Power Co., Ltd. Handan Power Supply Branch (referred to as Handan Power Supply Company) "Zhu Jinlei Innovation Studio", Zhu Jinlei was explaining the creative principle of "Electric Cat" to the students.

  Zhu Jinlei, 48, is the leader of the National Model Worker and Craftsman Talent Innovation Studio, a member of the CPPCC in Handan District, Handan City, Hebei Province. He is currently the director of Xinhe Comprehensive Energy Service Office of Handan Power Supply Company.

  Over the past 20 years, Zhu Jinlei has been focusing on anti-theft of electricity, and led the team to independently develop the "Electric Cat" anti-theft instrument to save a lot of losses for the country and enterprises.

According to the SG186 system of the State Grid, between 2009 and 2021 alone, the "electric cat" will recover over 100 million yuan in electricity bills.

  Zhu Jinlei was born in Handan District, Handan City. In 1995, after graduating from Shijiazhuang Electric Power Technical School Fengfeng Branch, 21-year-old Zhu Jinlei was assigned to the protection class of the Substation Branch of Handan Power Supply Company to become a secondary installer.

Due to his outstanding performance, in 2002, Zhu Jinlei was appointed as the director of Handan Liulin Power Supply Office, and his anti-stealing career began from then.

  "At that time, the power facilities of Liulin Power Supply Station were old, the power theft was serious, and the line loss rate was high. However, the operation of checking and stealing power was cumbersome and inefficient." Zhu Jinlei said, watching the country's power loss in vain, he secretly Determined to make an accurate theft detection instrument to improve the efficiency of theft detection.

  In March 2003, after painstaking research and development, he and his colleagues connected an ammeter, a parallel voltmeter, and a time relay to the box of a small box according to the watt-second method.

In this way, the first generation of electricity-stealing instruments was made.

  "With it, the time for checking electricity theft has been reduced from 10 minutes to 6 seconds. According to its function, colleagues named it 'electric cat' vividly." Zhu Jinlei said.

  With the popularity of smart meters, the tricks of stealing electricity are constantly being renovated.

In order to make these electricity stealing "rat" nowhere to hide, Zhu Jinlei's "electric cat" is also iteratively upgraded.

  In 2009, "Zhu Jinlei Innovation Studio" was established in Handan Power Supply Company. In 2020, Zhu Jinlei's studio has 31 R&D personnel. "Internet +" functions such as automatic collection and locking of electricity thieves are unique in the domestic anti-electricity theft field.

  For more than ten years, Zhu Jinlei and his team have completed 232 innovative achievements and obtained 51 patents, including 8 invention patents. For the 2020 national labor model.

  From "worker" to "artisan", Zhu Jinlei's road of innovation has not stopped.

Under his leadership, the studio has cooperated with a number of colleges and universities to carry out technical research, skills training, and personnel training, forming a technological innovation system with deep integration of production, education and research.

At present, there are more than 2,000 power supply system personnel trained by him, and more than 100 of them have been rated as national, provincial and municipal model workers or Hebei craftsmen, Hebei craftsmen, and professional technical leaders.

  Today, the project research of "Zhu Jinlei Innovation Studio" has also been extended from the simple "electric cat" theft detection instrument to the construction of smart grid, relay protection, high voltage test, etc., and the innovation work is in full bloom.

  "The master always teaches us 'innovate every day, make new every day, think about every day and grind every day'. He will always be a role model for me to learn from. Like the master, I will try my best to become an expert and expert on the job." " said Gao Peng.
