The information of the product with the name plate No. py - 600 meets the requirements and design documents of Chinese national standard GB / t25890.6 and International Standard IEC 61992.6.
The rectifier transformer (hereinafter referred to as transformer) is a dry transformer that mainly applies to the urban trolleybus traction substation.
The rectifier transformer (hereinafter referred to as transformer) is a dry transformer that mainly applies to the urban trolleybus traction substation.
Traction rectifier cabinet of trolley bus is mainly used to convert the AC voltage of rectifier transformer into 825V or 600V DC for subway or light rail vehicle traction, as the critical link of AC and DC conversion. In order to reduce the influence of harmonic currents on the grid, the rectifier currently adopt single cabinet 12-pulse rectification (composed of two three-phase 6-pulse full-wave rectifier bridges in parallel), and the traction substation generally consists of two rectifier units in parallel operation constituting equivalent 24-pulse rectification.

This equipment is indoor metal armoring with drawable switchgear (hereafter refer to as switchgear. 3.6-12kilovolt three phase AC 50Hz single bus bar and the single bus bar subsection system's omplete electricity distribution equipment is used in the power plant, small and medium-sized generator power transmission, industry and mining business power distribution as well as electrical industry system's second transformer substation's electric take-over , power transmission and large-scale high pressure motor starting and so on. The purpose is to control, protect and monitor. This switch equipment is up to the standard of IEC298、 GB3906 and can prevent the charge from pushing and pulling the breaker, from opening and closing the breaker, from insulation with electricity by mistaken, from earthed switch closing the breaker ,from opening the switch's interlock when it with electricity mistakenly. It can not only use with VS1 vacuum circuit-breaker, but with ABB Corporation's VD4 vacu
HXGN17-12 box fixed type metal-enclosed switchgear (switch cabinet for short) is used to receive and distribute electrical energy in 3.6, 7.2, 12kV three phase AC 50Hz system , specially in the frequ-ent operation occasion . Its bus bar system is single bus bar and it can derive single bus bar with branch and double bus bar structure. This switch cabinet conforms to the requirement of national standard GB3906-91 “3-35kV AC Metal Seal Switch equipment”and the international standard IEC298, and has the functionof “five prevention”. This switch cabinet's main switch is composed of ZN28A-12 Yu or the ZN22-12 series vacuum circuit breaker, the CD17A spring operating mechanism and the CT19B spring operating mechanism, the GN30-12rotary isolator and the GN22-10 big electric current isolator series product.
SRM6-12 inflatable SF6 metal enclosed fully insulated series bad mesh switchgear. Products are widely used in 10kV/6kV power distribution system, is a switch product for various types of urban and rural user power distribution system. The switchgear is modular unit mode, which can be combined according to different uses; There are two categories: fixed unit combination and scalable unit, to meet the flexible use of compact switchgear in various substations.
