Short circuit sniffer

21,22,23; And

electrical overloads sniffer

60,61,62.Each feeder line module 1 to 8 comprises

electrical overloads sniffer

24,24 instructions of this electrical overloads sniffer are called the trip gear of second trip gear 25, and described trip gear is designed to instruct the operating means 26 of the trip gear that is called

first trip gear

18,19,20 of

switch

15,16,17 of primary module 10.

Differential protection module 11 is included in the phase place of primary module and the differential detection device 27 on the neutral line in a conventional manner, and the operating means 28 of the trip gear that is called

first trip gear

18,19,20 of the switch of primary module 10.Differential protection module 11 also comprises two

earth terminals

29,30, and they are connected to each other and are designed to be connected on protector or the earthing conductor.

Also as shown in Fig. 3,4 and 5, this base modules 9 is held neutral terminal 31, and this neutral terminal 31 is designed to connect all outputs of feeder line module.This module is designed to locate and locate with respect to primary module on the other hand with respect to the feeder line module on the one hand by means of

alignment pin

32,33,34,50,51 (only showing the pin on circuit breaker one side).

As from Fig. 6 to 9 as can be seen, the operating means 26 that is called the

trip gear

18,19,20 of first trip gear comprises release lever 35, this release lever 35 is equipped inside the shell round being parallel to the axis X that the module alignment direction extends.

Shown in Fig. 8 and 9, release lever 35 comprises four parts, that is: straight beam 36, first end strutting piece 37, the second end strutting piece 38 and hinge bar 39.This hinge bar 39 is installed around above-mentioned axis X rotation with respect to shell, and passes all mechanisms of feeder line module 1 to 8.Described bar act as the pivotal pin of above-mentioned all mechanisms, and is positioned in the described base modules 9 that supports it.Above-mentioned two end supports 37,38 are respectively at two opposed

end fixing seals

40,41,

seal

40,41 be engaged in bar each end and with strutting piece that described end is associated between, the described seal system that makes can freely rotate and absorb any that may exist and alignment error pivotal pin.At the one end thereof place, each strutting piece comprises the part that opening 42,43 is provided, and the two ends that this part is extended length-specific and is designed to hold beam 36 on the direction of the axis that is parallel to this are used for beam 36 and are separately fixed at wherein.

At the place, end of location, aforesaid relatively end, two strutting pieces 37,38 also comprise counterweight 44,45 or flywheel, and in two is bigger than another, and the puppet when this counterweight is designed to prevent from product vibration to take place is threaded off.These counterweights provide a material weight, and its center of gravity that is arranged to release lever is positioned on the rotation of bar.

At the assembling position of release lever 35, second strutting piece 38 is fitted in the free-ended part that is positioned at the feeder line module of shell 52 (Fig. 6).Above-mentioned first strutting piece 37 is fitted in the base modules 9, with respect to it, the bar rotation cooperates, and this has guaranteed the good basis of bar with respect to this base modules 9, makes it always be in the tram with respect to the trip gear that is called

first trip gear

18,19,20 of primary module.

Above-mentioned first strutting piece 37 also comprises the bar 46 (Fig. 7, Fig. 8) that is called actuator lever, and actuator lever is parallel to beam extends on the direction of primary module, and is designed to activate the trip gear that is called first trip gear of primary module, as will be described further.

As shown in figure 12, the existence of spring 47 also should be mentioned, be engaged in the inboard of base modules 9, be fixed on first strutting piece 37 on the one hand, be fixed on the other hand on the strutting piece 48 of base modules, this spring is designed to bias stem to make and prevents to thread off when having vibration, by auxiliary this function of flywheel.In fact flywheel makes the size of spring be restricted, and reduces the pressure on the tripping mechanism of each feeder line module thus.

Therefore, this spring action is for preventing from explicitly to thread off owing to vibration is pseudo-with flywheel.

Release lever also comprises stop part, and the needle point that this stop part is designed to handle with the operator is worked in coordination with mutually, to carry out the test of threading off.The operator is inserted into needle point in the module by the hole that is arranged in the shell front panel.The self-adhesive label is placed on the hole, to hide this hole in module after after tested.

The operation of distribution board is described with reference to the accompanying drawings.

When the deflection enough owing to current overload has of one the bimetal strip of feeder line module 1 in 8, bimetal strip touches the release lever of the trip gear with breech lock, spring and mounting panel.Plate 49 contacts (Figure 10, Figure 11) with bar 35, drive rod counterclockwise rotates then, and this causes primary module 10 to be threaded off (Fig. 7) through above-mentioned actuator lever 46, causes electric current to be interrupted thus.

According to the present invention, release lever 35 is made of four parts thus, and they are easily molded and do not have a strain.Beam 36 is simple straight parts, and it can easily pass feeder line module 1 to 8.

First end strutting piece 37 provides four functions.It supports to center on the hinged of main shaft X, all alignment error of this hinged necessary compensation and the second hinged strutting piece 38.For this reason, the connection between strutting piece and the actuator lever is the hinged of universal joint type.

Long guiding by beam and with respect to the good basis of reference part 9, well secured and the good location that this has guaranteed beam 36 makes release lever always correctly locate with respect to the trip gear that is called

first trip gear

18,19,20 of primary module 10 (circuit breaker).

This end is also supported counterweight 44 and is supported the actuator lever 46 of the above-mentioned trip gear of primary module.

Second strutting piece 38 is carried out bar fixing, locating and guiding on opposite side.

Long metal shaft 39 or hinge bar support all mechanisms of feeder line module and bar.This is supported by the lid of base modules 9 and last feeder line module.This major axis 39 is benchmark of all functions parts, and realizes good alignment and always can excellent operation, even under the situation of the torsional strain greatly of this group feeder line module 1 to 8.

According to the present invention, made such release lever thus, this release lever is easy on different length to make and does not have strain, and is easy to assembling and passes all feeder line modules.

This bar can obtain excellent function, as perfection guiding and perfect location, reduces because the strain that the percussion in the operation is brought reduces because the puppet that vibration causes is threaded off, and have good durability under hot conditions.

Four parts of bar, promptly, beam, two strutting pieces and axle can assemble on production line.

The present invention is in no way limited to describe and illustrated execution mode at this naturally, and they only are in purpose for example and provide.The quantity of feeder line module therefore for example can be greater or less than 8.

On the contrary, the present invention extends to all technical equivalents that contain device described here.
