Übersetzung für "Trip relay" in Deutsch

If the current slightly exceeds the trip value, the relay armature begins moving upward.

Up to a defined tolerance range around the trip value, the relay reliably does not respond below the threshold but does respond reliably above it.

The circuit from Y 1 via the capacitor C 1 to the output Y 2 is closed by a thyristor T 1, in order to trip the relay 34 and/or the gate control 40 .

The residual current circuit breaker in question also comprises a trip relay 13 which is connected by circuitry to the two trip electronic systems 5, 7 by means of the diodes 19, 20 .

And some models, among other things, equipped with a timer, trip relay at a certain (programmed) time that the equipment did not work in vain.

The temperature of the flowing water and the cooling water discharged into the flow is measured via a temperature converter with trip value relay.

An economic solution can be implemented by using isolator modules with trip relays.

Frequent tripping of thermal relay - a serious reason to communicate with a specialist.

The evaluation unit 9 controls a triac 10 in the transfer circuit as amplifying member which, in its turn, actuates a tripping relay 11 which acts with its contact upon an explosive-actuated fast ground which is not shown in detail and which goes into grounding position within a very short period of time and thus short-circuits the interference arc and extinguishes it.

A secondary winding 57 is connected to a tripping relay 58 which is released by the switch latch 33 as well as are the thermal and the electromagnetic tripping devices 32a and 32, respectively.

Behind the tripping device 80, a sum-current transformer 82 is inserted, the secondary winding 83 of which actuates a tripping relay 84 which likewise acts upon the switch latch 77.

EP 0 570 603 A discloses a residual current circuit breaker which is dependent on the line voltage and in which the tripping relay is supplied between all three outer leads and the neutral lead.

The electronics of the residual current circuit breaker which is known from EP 0 570 603 A1 is however unable to turn off the load current which flows when tripped by the tripping relay, if the terminal for the load current is between the power supply line and the main contacts for the phase conductor.

This is done with the goal of finding an operating point on this trip characteristic curve, i.e., finding the exact point of intersection 62 at which the relay trips, or to put it more precisely, at which it makes the transition from the stabilization region 47 into the trip region 48 .

This always leads to tripping of the relay at lower fundamental mode current contributions, that is at lower thrust values.

In consequence, the relevant tripping identification relay 64 a does not operate the reset enable relay 62 c, as a result of which it, with its make contact which is then open, blocks the reset command via the corresponding line 60 from the signal output of the automation system 12 for the tripping memory 48 of the closed-circuit line 30 c .

Tripping identification relays and reset enable relays are provided for this purpose in the protective system, and block the resetting of the tripping memory in the abovementioned case.

A secondary winding 17 for the detection of a fault-current signal is further arranged on the summation current transformer 2, with the secondary winding 17 being connected through circuitry with at least one energy storage element 5 at least indirectly, and the energy storage element 5 being connected with a trip element 7 at least indirectly or cooperating with such a one, which is preferably arranged as a permanent-magnet tripping relay, which thus enables achieving an especially secure and rapid reaction of a residual-current circuit breaker 1 .

The two detection systems may each be formed from a core balance transformer and a tripping relay which is fed via the secondary winding of this core balance transformer.

However, a single core balance transformer is expediently provided for both detection systems, in which case the core balance transformer, which is preferably designed to detect both low-frequency and high-frequency fault currents, then has two secondary windings, which once again preferably feed a common tripping relay.

If a single core balance transformer with two secondary windings is used for both detection systems, high-frequency disturbance fault currents can lead to circulating currents flowing via the two detection systems and via the tripping relay.

If the relay 14 is used instead of the optocoupler 4, care must be taken to ensure that the relay tripping time is shorter than the checking time period of the program control apparatus 5 .

Since both rectifiers are preferably connected on the direct current side to a single tripping relay, a decoupling diode is connected in at least one of the two direct current circuits formed in this way.

While the zener diode in the first detections system limits the voltage across the tripping relay and prevents remagnetization (which would lead to a failure to trip) of the tripping relay in the event of high fault currents, preferably two series-connected zanar diodes in the second detection system additionally limit the disturbance voltages which are induced in that secondary winding of the core balance transformer which is associated with this second detection system.
