Problems solved by technology

On the other hand, it is disadvantageous that on one side the coil former is only held on the yoke by means of the plunger
This means that the bobbin contacts the plunger with its inner side, which leads to undesired frictional losses
In the absence of a spacer, the lug or the meniscus guide would have to be constructed spring-elastically, which might lead to excessive tolerances or relative movements between the former and the yoke
[0010] A disadvantage of this known electromagnetic circuit breaker is the complex structure or complex assembly of the elements of the electromagnetic circuit breaker
Applying cores or isolating elements means additional costs and increased assembly costs
Furthermore, in the prior art electromagnetic circuit breaker, the ejector pin partly contacts the bobbin, whereby friction loss occurs

Embodiment Construction

[0042] image 3 A longitudinal sectional view of an electromagnetic circuit breaker 8 for protecting a switchgear is shown. The bobbin 1 is arranged inside the U-shaped yoke 2 . The u-shaped yoke 2 has a base part 20 and two arms 21 , 22 each arranged perpendicularly to the base part 20 . Openings are provided in the arms 21 , 22 , in which openings the plunger 3 is supported. In this embodiment variant, the plunger 3 is designed in two parts, wherein the outer plunger part 3 b surrounds the inner plunger part 3 a. Furthermore, a spring element 6 is provided, which returns the plunger 3 to its starting position after removal of the voltage. The coil former 1 suspended in a U-shaped yoke 2 has a hollow-cylindrical body 5 on which a coil 7 is wound. The bobbin 1 has end plates 11, 12 on its ends each, on which a image 3 The protruding part in the middle is used to fix the bobbin 1 on the yoke 2 through the protruding part.

Abstract

A coil rack (1) of a solenoid-operated circuit breaker (8) of a protective switchgear is provided with a first terminal plate (11) and a second terminal plate (12) and a hollow cylindrical main body (5) arranged therebetween for housing a coil (7), on an end side axis direction of the first terminal plate (11) and the second terminal plate (12) parallel with a longitudinal axis of the hollow cylindrical main body (5) of the coil rack (1), at least a projecting part (13) is arranged fixed to a yoke (2). The yoke (2) having a U-shaped contour of the solenoid-operated circuit breaker (8) of the protective switchgear has a basis part (20) and two arms (21, 22) arranged thereon, and a recess respectively in each arm, for penetrating a guide mandril (3), at least one groove (23) is respectively arranged on the end side of the first arm (21) and the second arm (22) of the yoke (2), for housing the projecting part (13) of the coil rack (1) in shape match. Provided is a solenoid-operated circuit breaker (8) and a protective switchgear.

Description

technical field [0001] The invention relates to a coil frame of an electromagnetic circuit breaker for protecting switchgear, which has a first end plate and a second end plate and a hollow cylindrical body arranged between the end plates for accommodating a coil. The invention also relates to a yoke for an electromagnetic circuit breaker for the protection of switchgear, having a U-shaped profile, comprising a base and two arms arranged on the base and a respective recess in each arm for To run through and guide the ejector rod. The invention also relates to an electromagnetic circuit breaker with a protective switching device having a coil former and a magnetic yoke, and to a protective switching device. Background technique [0002] Protective switching devices enable safe contact with electrical energy. Firstly, the increasing use of fault current (FI) protective switches and line protective switches (so-called LS switches) contributes to increased safety. The combine...
