Description

(54) TIGLLER CURRENT

one

The invention relates to electrical engineering, in particular, trolley-wire current and devices used for the electrification of mobile lifting and transport mechanisms.

Trolley busbars are known for powering electric receptacles of bridge cranes. Trolleys of these conductors, mounted on insulators, are fixed with the help of 1 stolts on the crane girders 1.

The design of these TOKOFREEES is complex and cumbersome and time consuming to manufacture and m (installation time).

Also known are trolley tokolrovye devices - shsh {O1fovod1 types ShTM 70 and ShTM 72. Etn current conductors of the wave {s in the form of separate sections of steel sheath, having below a solid slit for the jogging of a current-collecting device. T-shaped trolls 12 are simulated inside the casing in the slots of the nzol tsfov.

However, current conductors have a new operational reliability due to the presence of dynamic and vibration loads created by collector devices during the passage of sec.

The purpose of the invention is to increase the reliability of the current conductor.

This goal is achieved by the fact that in a well-known trolley-type current lead containing a current-carrying head with an insulator supporting it, w, enclosed in a shell, and a movable current collector with a holder mounted on an electric receiver. The insulators are made in the form of an equilateral angle with a length of half a kiln more than the transverse gabrints of the current collector holder and hinged on the shell, and the current-carrying wire is mounted on the insulators freely.

Trolley TOKO1FOVOD contains tokkeschishchi wire 1, sheath 2, iaol tppy 3, installed by the hinge with fingers 4

The current-carrying 1 is suspended for the entire span length and tensioned, and the shell 2 is made of individual sections, fixed, nahfimer, to the crane girder using special fasteners (not shown). Insulators 3 are made in the form of a diverse angle and are installed in steps that exclude excessive current sagging of conductor I in conduit 2, which is placed on them. Current collector 6 is designed as a camphor inside which is mounted a state removable eshom (shown in the drawing). Tokonesuots i tovod 1 passes through the current collector chamber 6 When moving in tauko tOKOciiiieME3Na 6, its holder 7 exchanges the isopost (90 ° of them.) As far as it is rotated, it isolates 3 of them ( The rail | TS11y floyod 1 is gently lowered onto these insulators. When moving in the opposite direction t (slots No. 3 turn on the initial gate and this results in a great impact on the current of the capacitor) ozod. operational reliability, simplifies chrfuction.

The mSt HiTOB is a current collector and a wire clamp on the wedge of everything, and the FUELD set the isolator to the isolator freely. Itochiykm, admitted to heed during the etcepsis 1.
