PESA SA
Pesa (Pojazdy Szynowe Pesa Bydgoszcz) is a Polish company manufacturing Rolling stock, railway vehicles based in Bydgoszcz. The name 'Pesa' derives from the initials PS which stand for ''Pojazdy Szynowe,'' 'railway vehicles' in Polish. Pesa is a successor to the Bydgoszcz repair shops of Polish State Railways, PKP ''Polskie Koleje Państwowe,'' Polish State Railways. From the 1950s until 1998 the repair shops operated under the name ZNTK Bydgoszcz, ''Zakłady Naprawcze Taboru Kolejowego,'' 'Repair Shop for Railway Rolling Stock' in Bydgoszcz. For most of its history the Bydgoszcz shop overhauled and repaired steam locomotives and freight cars. After the End of Communism in Poland (1989), collapse in 1989 of the Communist regime in Poland the ZNTK Bydgoszcz repair shop was spun off in 1991 as an independent company. This led to a re-thinking of the firm's activities, and in 2001 the company was renamed ''Pojazdy Szynowe Pesa Spółka Akcyjna Holding'' (its present name) and its ...

Konstal 105Na
The Konstal 105Na are a class of Polish trams manufactured from 1979 to 1992 in workshops Konstal Chorzow, Poland. The Metre-gauge railway, meter-gauge version is designated as 805Na. As of 2016 they are still the most common trams in Poland. Construction 105Na is unidirectional motor tramcar, equipped with four doors. It is a development of the earlier Konstal 105N. The main changes being a shift in the location of the electrical equipment from under the steps to the back wall of the driver's cabin, the introduction of a separate cabin for the driver, as well as the removal of the small windows under the front and side windscreens. The most important change was the introduction of motor grouping, which reduced the energy consumption by 12%. During initial acceleration, the four motors are connected in series, whilst at higher speeds, two groups of motors are connected in parallel. While in service, the 105Na vehicles were the subject of various modifications and upgrades (includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thyristor
A thyristor () is a solid-state semiconductor device with four layers of alternating P- and N-type materials used for high-power applications. It acts exclusively as a bistable switch (or a latch), conducting when the gate receives a current trigger, and continuing to conduct until the voltage across the device is reversed biased, or until the voltage is removed (by some other means). There are two designs, differing in what triggers the conducting state. In a three-lead thyristor, a small current on its Gate lead controls the larger current of the Anode to Cathode path. In a two-lead thyristor, conduction begins when the potential difference between the Anode and Cathode themselves is sufficiently large (breakdown voltage). Some sources define silicon-controlled rectifier (SCR) and thyristor as synonymous. Other sources define thyristors as more complex devices that incorporate at least four layers of alternating N-type and P-type substrate. The first thyristor devices were ...

Resistor
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. High-power resistors that can dissipate many watts of electrical power as heat may be used as part of motor controls, in power distribution systems, or as test loads for generators. Fixed resistors have resistances that only change slightly with temperature, time or operating voltage. Variable resistors can be used to adjust circuit elements (such as a volume control or a lamp dimmer), or as sensing devices for heat, light, humidity, force, or chemical activity. Resistors are common elements of electrical networks and electronic circuits and are ubiquitous in electronic equipment. Practical resistors as discrete components can be composed of various compounds and forms. Resisto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tram
A tram (called a streetcar or trolley in North America) is a rail vehicle that travels on tramway tracks on public urban streets; some include segments on segregated right-of-way. The tramlines or networks operated as public transport are called tramways or simply trams/streetcars. Many recently built tramways use the contemporary term light rail. The vehicles are called streetcars or trolleys (not to be confused with trolleybus) in North America and trams or tramcars elsewhere. The first two terms are often used interchangeably in the United States, with ''trolley'' being the preferred term in the eastern US and ''streetcar'' in the western US. ''Streetcar'' or ''tramway'' are preferred in Canada. In parts of the United States, internally powered buses made to resemble a streetcar are often referred to as "trolleys". To avoid further confusion with trolley buses, the American Public Transportation Association (APTA) refers to them as "trolley-replica buses". In the Unit ...

Bydgoszcz
Bydgoszcz ( , , ; german: Bromberg) is a city in northern Poland, straddling the meeting of the River Vistula with its left-bank tributary, the Brda. With a city population of 339,053 as of December 2021 and an urban agglomeration with more than 470,000 inhabitants, Bydgoszcz is the eighth-largest city in Poland. It is the seat of Bydgoszcz County and the co-capital, with Toruń, of the Kuyavian-Pomeranian Voivodeship. The city is part of the Bydgoszcz–Toruń metropolitan area, which totals over 850,000 inhabitants. Bydgoszcz is the seat of Casimir the Great University, University of Technology and Life Sciences and a conservatory, as well as the Medical College of Nicolaus Copernicus University in Toruń. It also hosts the Pomeranian Philharmonic concert hall, the Opera Nova opera house, and Bydgoszcz Airport. Being between the Vistula and Oder (Odra in Polish) rivers, and by the Bydgoszcz Canal, the city is connected via the Noteć, Warta, Elbe and German canals with t ...
