Problems solved by technology

This misinterpretation of the safe state can cause significant injury and damage to the switchgear
It is important to note that simply teaching users how to use a portable arc protection system may not be enough, and the same consequences may result from lack of care and focus of maintenance personnel, possibly due to time constraints when repairing damaged switchgear

Embodiment Construction

[0074] In general, the same or similar parts are denoted by the same / similar names and reference numerals. Features disclosed in the specification apply to parts with the same / similar names and reference signs. Indications of orientation and relative position (up, down, sideways, etc.) are relative to the associated figure and must be modified accordingly in different figures as the case may be.

[0075] figure 1 The wiring scheme of a protection system 1a of the proposed type is shown. The protective system 1a comprises a switchgear 2a with a compartment A for receiving a slide-in unit 3a and a plug-in figure 1 The slide-in unit 3a in the compartment A of the switchgear 2a.

[0076] In this example, the switchgear 2a comprises two switching devices 4, 5 each comprising three switching contacts, a mains power system 6 connected to the switching devices 4, 5, and a first ( metal) main connector 7a.

[0077]The slide-in unit 3a comprises a short-circuit switch 8a, a second ...

Abstract

A protection system (1a..1h) with a switchgear (2a..2e) having a compartment (A) and a slide-in unit (3a..3e) in this compartment (A) is disclosed as well as a method of inserting the slide-in unit (3a..3e) into the compartment (A). The switchgear (2a..2e) comprises a switching device (4, 5) and a main power system (6) with first main connectors (7a, 7b). The slide-in unit (3a..3e) comprises a short circuit switch (8a..8c) connected to second main connectors (9a, 9b), and an auxiliary power system (10) for powering a control unit (11a, 11b) controlling the short circuit switch (8a..8c) and for powering at least one sensor (13a..13d) connected to the control unit (11a, 11b). The electric connection to the auxiliary power system (10) is established at a first slide-in position (B), and the electrical contact between the first and second main connectors (7, 9) is established at a second slide-in position (C), which is reached after the first slide-in position (B) during insertion.

Description

technical field [0001] The invention relates to a protection system comprising a switchgear having a compartment for receiving a slide-in unit and a slide-in unit designed to be inserted into said compartment of the switchgear. Furthermore, the switchgear comprises at least one switchgear, a main power system connected to the switchgear, and a first main connector electrically connected to the main power system and arranged in a compartment of the slide-in unit. In addition, the slide-in unit includes a short-circuit switch and a second main connector electrically connected to the short-circuit switch and electrically connected to each other in an on state of the short-circuit switch and in an off-state of the short-circuit switch. electrically disconnected from each other. Finally, the slide-in unit comprises an auxiliary power system for powering the control unit connected to the control input of the short-circuit switch and for powering at least one sensor connected to the...
