20081017

The utility model discloses an assembly structure for a contact

compression spring of a medium-voltage vacuum circuit-breaker in

a power distribution system, which comprises an insulating draw rod

(3) whose one end is provided with an insert (6), a disk spring (2), a

connecting rod (8) whose middle portion is provided with a flange,

and a sealing nut (1) whose middle portion is provided with a round

hole, wherein a guide groove (7) is arranged on the bottom of the

insert (3), and the lower end of the connecting rod (8) is penetrated

through the disk spring (2) into the guide groove (7) of the insert.

When the connecting rod (8) moves up and down, the lower end of

the connecting rod is still in the guide groove (7), thereby avoiding

the friction and clamping stagnation phenomenon between the

connecting rod (8) and the dish spring (2), and increasing the

performances of the vacuum circuit-breaker.

functional components of the switchgear assembly is replaced by a

wiring in a box (1) or a panel and that the electrical components

(20) are each connected directly to the box (1) by means of a

bundle of bound cables (30). Another essential embodiment

provides a coding plug for being plugged from the exterior.

The device (100) has voltage-guiding component such as two

contact pieces (101, 102) and two connecting pieces (103, 104) that

are totally enclosed in a packaging (105). The packaging is filled with

a filling medium (109) that contains a compound from a group of

perfluorinated ketone. The packaging is provided with an openable

and again-lockable closure element. The filling medium serves as an

electrical isolation medium and/or an arc quenching medium. The

connecting pieces are surrounded by bellows (108). An independent

claim is also included for a method for filling a packaging.

The aim of the invention is to devise a switch module (1) for medium-

voltage switchgear (24), which module allows a compact and

space-saving design of the medium-voltage switchgear (24). The

switch module (1) for medium-voltage switchgear (24) according to

the invention has a housing (2) which is provided with fastening

means (11) for holding elements (9) and fastening elements (10) of

switching devices arranged in the switch module (1) in such a

manner that the housing (2) can be embodied as an insulating

housing and as a support housing for the switching devices.

The invention relates to a gas insulated medium voltage switchgear

with a 3 position disconnector device for 3 electric phases on one

common rotatable driveshaft. In order to realize a common

construction, the three position disconnector device for three phases

is arranged in one common functional unit, which has a base plate

and a frame, and which can be mounted in a switchgear housing, in

that way, that the baseplate and/or the frame is after the mounting

a part of a gastight housing of the switchgear.

The invention relates to an improvement to the thermal load

capacity of generator switches (20, 21, 22). As is known, radiation

plates (5, 50, 51, 52) are used between generator switches (20, 21,

22) for different phases (R, Y, B) for convective dissipation of radiated

heat from adjacent encapsulation side walls (30b). According to the

invention, in the vicinity of the encapsulation cover (3a) of a

generator switch (20, 21, 22), the radiation plate (5, 50, 51, 52) has at

least one angled metal sheet (50a) which is used to guide at least

one air flow element (9) of the rising air flow (9) in the direction of the

encapsulation cover (3a) and in order to direct the flow along the

encapsulation cover (3a). Exemplary embodiments include:

radiation plates (5, 50, 51, 52) electrically and thermally isolated from

the housing (3); radiation plates (5, 50, 51, 52.) with horizontally

deflecting air guidance structures (5la, SIc) on the inner face (Sa);

angled metal sheet (50a) whose inclination is matched to a

flattened area (30a) on the encapsulation cover (3a); angled metal

sheet (50a) directed at cooling elements (6) on the encapsulation

cover (3a). Advantages include: generator switches (20, 21, 22) with

improved heat emission, increased rated current carrying capacity,

and/or a more compact configuration.
