Opis:: The paper presents the test results for the microstructure of ZnO varistors comprising high voltage gapless surge arresters. The tests were performed on varistors produced in different periods and by various manufacturers. The research was inspired by different characteristics of changes in values of current flowing through surge arresters as a function of changes in values of system voltage in a 220 kV substation, and the temperature in a multi-year cycle. Furthermore, the effects of varistor microstructure degradation following a failure of an unsealed surge arrester were investigated. The results provided the grounds for assessment of ZnO varistor microstructure parameters in terms of their durability and resistance to degradation processes.

Opis:: The paper presents investigations of microstructure of varistors of damaged surge arrester counters. A similar ZnO varistor, not subjected before to operation, was a point of reference in this research. The results of investigations of the ZnO varistors show an untypical phase composition of their material, which was characterized by unsatisfying homogeneity and cohesion. The degradation processes of varistor material in the subsequent stages were recognized and described. A harmful impact of humidity inside the untight surge arrester counter on its operation and its ZnO varistors was proved. Some conclusions being the result of the operation checking of surge arrester counters were presented too.

Opis:: The work analyzes the possibility of using a truck chassis in terms of installing a specific device. As part ofwork was selected the vehicle, identified the necessary geometric parameters and the mass allowing of modernization, with particular emphasis on the required structural changes in the front and rear suspension. To this were used, the developed two phase methodology of calculation of the metal elastic elements (springs) and mechanical lateral tilt stabilizers. Results of numerical calculations are presented in the form of recommendations to redesign of the front and rear suspension. However, in the front suspension should be made a new spring and a mechanical lateral tilt stabilizer, while rear spring suspension meets the requirements in terms of elastic characteristics (adequate the coefficient of rigidity) is requiredonly adjustment of the static deflection of the suspension for example by adjusting the radii of leaf of the spring. Because of the design solution of the driving rear axle (so called driving axle trolley) was not proposed mechanical lateral tilt stabilizer. Paper present diagram of the forces acting on a vehicle with special equipment, results of the calculation loads acting on the suspension components fitted to a lorry with a special device, results of the calculation loads acting on the base vehicle suspension components, the basic parameters of a lorry with special hull and performance graph of the front suspension leaf spring resilience.

Opis:: The aim of this researches was to identify all functional blocks of tank gun stabiliser 2E28M (installed in tanks T-72 and PT-91 Twardy) in order to build mathematical model of the system. The tank gun stabiliser is an electro-hydraulic control system, which makes possible aiming at a target, tracking of a target and stabilise of a given gun and turret angular position. The two-axial stabiliser consists of two separate control systems to stabilise the gun in elevation and the turret (with gun) in azimuth. After detailed analysis of construction and work principles, functional schemes of investigated systems were build. Afterwards, static and dynamic characteristics of functional parts of the system were determined. Because of obtained characteristics and based on the knowledge about the system feedbacks, structural schemes and mathematical models of foregoing stabiliser were derived. The results of numerical computations were compared with the existing results of experimental tests carried-out on a real plant. The results of experimental and model simulation investigations showed that the mathematical model and its numerical implementation were correctly developed.

Opis:: The paper describes dynamic load-generating sources and their effects on combat vehicles (CV), placed people and equipment within it. The variety of the operation conditions causes a complex dynamic load, both in terms of level, direction and distribution. The effects of the impacts are shown in photographs. It is important to know the level of loads in terms of the development of resistant and safe high-speed tracked combat vehicles. The selected results of its own researches of high-speed tracked combat vehicles were presented. Research were carried out under conditions similar to those typical for this class of vehicles, both during the rides on the road, the ground and obstacles on the specially constructed for this purpose. The results of research and analysis are compared in the form of graphs and the estimated value. The paper presents angular movement of the hull of the CV as well as displacements of carrying wheels during overcoming a single obstacle, elastic characteristics of hydro-pneumatic suspension components, distribution of pressure acting on a selected area of the bottom of the hull after mine explosion and power spectral density estimator of tank gun vibration as well as being the source longitudinal vibration of the hull tank. The presented scope and methodology allows the multi-variants investigation and estimate the loads of the hall, interior fittings and people in special vehicles and other objects that may be exposed to this type of loads.

Opis:: The paper presents results of investigation of microstructure and micro-hardness for material of ZnO varistors applied to 110 kV surge arrester and surge arrester counter. The research combined two pairs of varistors, each consisted of one varistor subjected before to operation, while the other one was brand new unit and constituted a reference. All varistors were made of the same material by the reputable manufacture. The tests revealed a different degree of the material degradation for varistors subjected before to operation. This also refers to different degradation mechanism observed for the material of these varistors, if typical effects of degradation of aged ZnO varistors were considered as a reference. Physical state of spinel in the microstructure had a significant impact on the material degradation, however a considerable loosening of the microstructure associated with bismuth oxide was observed too. It was surprising, since the precipitates of the bismuth oxide phase most often showed very good binding to the ZnO matrix and high resistance to associated electrical, thermal and mechanical effects. The degradation effects in the ZnO matrix proved to be limited only.
