Description

The utility model relates to electrical engineering, in particular to sources (accumulators) of energy operating in pulsed high power modes in maritime transport, that is, in conditions of strong rolling.

Known battery of electrochemical capacitors (ECC) according to the patent for the invention of the Russian Federation No. 2260867, publ. 09/20/2005, containing a housing with current leads, as well as a set of ECC placed in the housing (at least two). The capacitors are electrically connected by jumpers to each other and to the current leads of the battery and are combined into a single unit by a device preloaded ECC, which consists of a clamp, a spring and an interlayer plate between the clamp and the spring. The preloaded device provides "preloading" of capacitors. The spring compensates for the gaps between the capacitors and the shells formed during the manufacturing process. The compression of the capacitors in the block is a very important condition for the operation of the battery; its capacity and energy depend on the compression force.

The block of capacitors is installed in the case with a gap, therefore, in the process of moving the battery or when the case vibrates, the possibility of block displacement in the case is not excluded. In such cases, the known preload device cannot protect the capacitor bank from damage during battery operation.

Closest to the claimed is taken as a prototype battery based on electrochemical capacitors (RF patent for utility model No. 198028, publ. capacitors, which are fastened into a block using a spring-loaded clamp and electrically connected to each other and to the battery output terminals by metal jumpers between the ECC borns, supplemented by a spacer bar installed between the side walls of the case and the ECC borns, while the case cover is equipped with protrusions in contact with the spacer bar and pushing it to the block of capacitors.

The disadvantage of the prototype is the lack of means to compensate for electrolyte splashing out of the capacitor housings during strong pitching, getting it into the switching points of the borons, electrolyte leakage from the emergency valve, which causes an increase in contact switching resistance, an increase in leakage currents and reduces battery performance.

The problem of developing designs of leaky batteries of electrochemical capacitors with alkaline electrolyte is a limited service life.

The technical result of the utility model is to reduce the impact of corrosion on switching elements due to the ingress of electrolyte onto them, which occurs under mechanical loads associated with strong pitching.

This problem is solved by the proposed battery design based on electrochemical capacitors.

A battery based on electrochemical capacitors contains a case with a cover with a set of at least two electrochemical capacitors installed in it, fastened into a block using a spring-loaded clamp and electrically connected to each other and to the battery output terminals by metal jumpers between ECC borns, a spacer bar installed between the side walls of the case and ECC borons, and the case is made welded from corrosion-resistant steel, the battery terminals are connected to the end borons of the busbars and brought out into the holes in the cover, a layer of organosilicate composition with high dielectric properties is applied to the inner surface of the case, the volume of the case between the side walls and capacitors, and between the capacitors it is also filled with a silicone electrical insulating compound, ECC borons are coated with a protective lubricant.

The casing made of corrosion-resistant steel with the help of welded joints provides reliable fixation of capacitors in the battery, as well as increased resistance to both internal and external corrosion, as well as rapid removal of heat generated during battery operation. Mounting the output terminals on the busbars ensures their fixation relative to the electrochemical capacitors of the battery, and also prevents the terminals from overheating when passing a current of up to 200 A. Applying an organosilicate composition with high dielectric properties to the inner surface of the case, for example OS 12-03 paste, eliminates leakage currents through the case. Filling the free volume of the case with a silicone electrical insulating compound, for example, Viksint PK-68, dampens the vibration of battery cases based on electrochemical capacitors, which, in turn, prevents the penetration of electrolyte to the switching parts, which prevents their corrosion and ensures reliable operation even under significant mechanical loads, generated by the rolling of a sea vehicle.

Coating of burs with protective lubricant, for example ZES TU 38.101474-74 rev. 1, 2, 3 (Protective Electric Network), used to protect against corrosion of ferrous and non-ferrous metals in all climatic zones and conditions of sea fog and contact with sea and fresh water, as well as with direct exposure to sunlight and heating of surfaces up to 100 ° C , prevents corrosion of borns when electrolyte gets on them.

Thus, the set of essential features of the utility model provides the claimed technical result.
