Description
【考案の詳細な説明】 ［産業上の利用分野］ 本考案は、密閉形鉛蓄電池の改良に関するもので特に大
形で期待寿命の長い電池に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an improvement of a sealed lead acid battery, and more particularly to a large battery having a long expected life.

メンテナンスを必要としない等の利点がある。[Prior Art] In recent years, even in a large-sized stationary lead-acid battery, a glass fiber mat that holds a liquid has been developed, and a sealed lead-acid battery that does not leak has been created. Since this battery retains liquid, it can be used in any orientation. Further, there is an advantage that no maintenance is required because there is no need for replenishing water.

は言えないのが現状である。[Problems to be Solved by the Invention] However, large-sized stationary lead-acid batteries are required to have high reliability because they are used as an emergency power source for telephone stations, hospitals, buildings, and the like. Therefore, if it is possible to know the likelihood of occurrence of the defect before the defect occurs, the reliability is enhanced. Several attempts have been made with regard to battery capacity, but leakage has not been considered. Since the electrolytic solution is an aqueous sulfuric acid solution, the leaking liquid causes great damage to other devices. In particular, this liquid leakage has the largest liquid creep at the pole column sealing part, and it cannot be said that it will not completely leak in the longevity of 10 to 20 years.

ことを特徴とするものである。[Means for Solving the Problems] In the present invention, a sensor for detecting impedance between a pole pillar by contacting the pole pillar is embedded in the pole pillar sealing portion, so that the pole pillar sealing portion is electrolyzed. It is characterized in that when the liquid rises, the impedance of the contact portion between the pole and the sensor is increased to detect the leak of the sealed storage battery in advance.

いる。[Embodiment] An embodiment of the present invention will be described below. In the pole post sealing portion, a copper piece, which is a metal soluble in sulfuric acid, is fitted as a sensor 3 into the pole post 2, and an epoxy resin 5 is used to seal the gap with the battery case 4. The electrolyte rises around the poles,
When the copper piece of the sensor 3 which is in contact with the pole 2 is corroded, the impedance between the pole 2 and the sensor 3 is changed by the impedance measuring device 1 if the impedance measurement device 1 continues to measure the impedance. The rise of the electrolytic solution can be detected. The sensor 3 is embedded in the vicinity of the center of the sealing portion for the purpose of detecting before leaking to the outside.
