ACCUMULATORS WITH TUBULAR PLATES (PZS)
WITH THE POSSIBILITY OF WATER REFILLING
- lifetime is not less than 10 years under autonomic operating
- lifetime is 15 – 17 years with backup supply
- chemically pure plumb alloy
The company “MicroART” offers for sale the following most durable AB: MICROART’S LEAD-ACID OPEN TYPE TRACTION AB with tubular plates (WITH THE POSSIBILITY OF WATER REFILLING). Recommended to provide full autonomy and/or for backup systems. AB MicroART lifetime is not less than 10 years under autonomic operating with correct operation (or 80% depth of 1500 discharge (DOD) cycles) or 15 – 17 years with backup supply. Delivered in dry-charged state. Buying of liquid electrolyte is required (they are filled up on-site). They become practically hermetically sealed after installing of recombination plugs what maintains the best durability parameters.
Tubular plate AB represent the wide class of high-quality lead-acid accumulators built on the lattice structure plates with tubular electrodes. The so-called tubular positive plates, every component of which is encased in an acid-permeable polymeric bar, are made of chemically pure plumb alloy (metal purity is not less than 99,9%) and 2 – 6% of antimony.
This technology is used for all durable industrial types of AB (tractive, stationary, solar, both low-maintenance and sealed) with a long lifetime.
Traction AB may be used in electric hoists and other kinds of electrical machinery. Usually, a battery pack for required voltage is made of 2 V high-capacity batteries (1200 А·h).
The mentioned traction AB are made by tubular plate technology and refer to tractive, but they can be successfully used for autonomous and uninterruptible energy supply. Their standard labeling – Low-Maintenance PzS (is the German abbreviation of “Panzerplatten Standard”).
An accumulator is composed of the block of positive tubular plates and the negatives lattice plates. That construction of the positive plates prevents their faster destruction and provides long accumulators lifetime in general. Tubular plate accumulators stand at least 1500 charge-discharge cycles before the AB capacity drops by 20-25%.
The standard family (2 V accumulators are connected in series to provide 12, 24, 48 or 96 V required voltage) is the following: • 210 А·h 2 V • 400 А·h 2 V • 720 А·h 2 V • 960 А·h 2 V 2 V accumulators have a capacity up 960 А·h that allows to reduce their total number.
Also, special plugs with catalysts for hydrogen recuperation are offered. It allows to reduce the requirements for room ventilation and the likelihood to miss out electrolyte level checkup, what may cause the premature AB damage. There are two types of catalysts operating with the AB up 500 А·h to 1000 А·h). As a result, the requirements to the necessity of room ventilation are reduced in many times! It is advised to check up electrolyte level (for water refilling, if necessary) only 1 time every 3 – 6 years (it depends on the use intensity).
