Embodiment
Fig. 1 shows a kind of schematic diagram according to the utility model discharger overload detector 1.Wherein, described device It is arranged to be used for detecting discharger overload.Therefore, described device 1 has inductive coupler L, known using the coupler Do not pass through the electric current I for the discharger A to be monitoredA.Described device also has a switching equipment SE in addition.
The first electric current I is reached in coupler1When, just triggering switches equipment, wherein, the handoff procedure of switching equipment is to pass through Electric conductor F1The action of mechanical or thermal type disconnect caused by.
Wherein, the electric conductor F1It is not a kind of necessarily fusing conductor, but various dimension sizes can be used Conductor.
Here, the first electric current I1It is inductively by the electric current I by the discharger AAIt is caused.
Due to inductive, therefore, the generation of electric current and voltage equivalent to electric discharge.Therefore, the first electric current I of coupling1With Electric current allows to be inferred to electric energy immediately.
Therefore, the equipment is to be based on transformer principle.Wherein, the electric discharge that such as coil L will so with the discharger A Path is mutually attached troops to a unit, so as to form magnetic couplings.Here, the coil can be implemented as discrete parts, but it can also be carried out To be integrated in a circuit board.
Being shown as the switching equipment SE of dashed square kenel in Fig. 1 can further enter in the other drawings Row explanation.
The switching equipment SE can be implemented with relay as shown in Figure 2.In the event of corresponding high electric current I1, then, the relay R can apply a kind of active force, and the thus conduction on the electric conductor for be shown as lines Body bears pulling force, so as to occur compressing and separate.
The relay can also be implemented as bistable.Filled if by the L electric energy for being transfused to the switching equipment SE Foot, then the relay R is just triggered.Otherwise it can reset.Wherein, the relay R can also still have more zero Part, such as capacitor, correspondingly to set switching characteristic.
The relay R can be added directly or indirectly on the electric conductor of the discharger A herein, and for example be triggered Open circuit.The relay R may be additionally used for providing extensive machinery and/or electric signal conveyer AL.This arrangement is applied to Each type of discharger A, and it has been provided in particular in the electric isolution of signal transmission and discharger potential.By it is above-mentioned it is simple, Rational construction, can be to cost advantages and the mode that can be retrofitted on existing discharger A constitutes described device 1.
On the other hand, the switching equipment SE can be implemented with one or more fusing conductors as shown in Figure 3 F1、F2、....Each fusing conductor F1、F2... it can be constructed so herein, i.e.,：So that it has another fusing integration I2T, So as to separate the maximum electric discharge for being accurately inferred to occur by one or more of fusing conductors.
So it can for example be recognized by the setting of the fusing conductor, whether the ceiling capacity load of the discharger A meets.
First electric conductor F1It can for example be practiced so that it in the first electric current I1Under conditions of trigger, and the Two electric conductor F2Then it is practiced so that it in the second electric current I2Under conditions of trigger.Wherein, the first electric current I1It is smaller than Second electric current I2, as just as indicated by the accompanying drawings by the lines of different in width.
The signal transmitter AL is directly or indirectly connected with the electric conductor, and the signal transmitter is for example added Spring D is carried, so that the signal transmitter AL is stored in the electric energy in the spring D when the electric conductor is separated in release Under conditions of complete corresponding conversion.
That is, by appropriate setting, the strain that completed can be shown.These exemplary embodiment party Formula is illustrated in Fig. 3,5 and 6.Wherein, various forms of signals can be used to transmit.
For example show a kind of mechanical signal transmitter AL, wherein, the letter with different transparencies or colour gamut Number plate is either moved directly or indirectly, thus shows the region corresponding with state.Therefore, signal transmitter AL Active force can be for example loaded, such as by spring D pretensions.Such as described signal plate can be moved by the shell G of the switching equipment SE It is dynamic, just as shown in Fig. 6.Alternative or additional project are that for example flexible element can be pressed corresponding Button and thus trigger remote notification.
