Leakage protector, also known as leakage switch, is a new type of electrical safety device, mainly used for: ZHEJIANG QIANNA ELECTRIC CO.,LTD , https://www.traner-elec.com
Wuhan held the 2008 industry patent early warning report seminar and conference, and for the first time, it carried out patent early warning mechanism for the three major industries of power storage vehicles, LEDs and photonic crystals in the new economic field, so that patent disputes were prevented.
According to the introduction of the Wuhan Municipal Intellectual Property Office, the patent early warning mechanism refers to the collection and analysis of patent information and domestic and foreign market information in the technical fields and related technical fields of the industry, to understand what competitors are doing, and to show the precursors and possible patent disputes. The resulting hazards, etc., suggest a mechanism for industry organizations and industry players to take countermeasures.
Yesterday, the new energy vehicle patent countermeasures, high-power LED patent countermeasures, and photonic crystal patent countermeasures early warning report were released.
It is understood that if you can effectively use patent information, not only can shorten the development time by 60%, but also save 40% of research and development expenses.

(1) Prevent electric shock accidents caused by electrical equipment and electrical circuit leakage;
(2) Preventing single-phase electric shock accidents during electricity use
(3) Timely cut off single-phase grounding faults in the operation of electrical equipment to prevent fire accidents caused by leakage
(4) With the improvement of people's living standards and the continuous increase of household appliances, personal electric shock and fire accidents caused by defects, improper use, and inadequate safety measures of electrical equipment in the process of using electricity have brought undue damage to people's lives and property. The emergence of leakage protectors provides reliable and effective technical means for preventing various accidents, timely cutting off power, and protecting equipment and personal safety.
The leakage protector should meet the following technical requirements
(1) The sensitivity of electric shock protection should be correct and reasonable, and the starting current should generally be within the range of 15-30 milliamperes
(2) The action time of electric shock protection should generally not exceed 0.1 seconds
(3) The protector should be equipped with necessary monitoring equipment to prevent it from losing its protective effect when the operating state changes. For example, for voltage type electric shock protectors, a neutral grounding device should be installed.
