Claims (22)

An output device that outputs a higher level of interception signal than the monitoring signal or monitoring signal, a buffer device installed between the output device and the bus to which the signal is supplied, and the presence of the monitoring signal. Supervisory detectors, inter-trip signal transmitters that allow the trip signal to be supplied by the output and applied to the bus, and trip detectors that detect the presence of an trip signal on the bus to perform trip control functions at the station. Interstation station comprising a. The station of claim 1, wherein the output device is a DC to DC converter. 3. The station of claim 2, wherein the converter comprises a pulse width modulator. 4. The station of claim 3, wherein the pulse width modulator operates in a constant energy pulse mode. 5. A shock absorber according to claim 4, wherein the shock absorber consists of a pulse transformer having a primary winding and a secondary winding, the primary winding being controlled by a converter to provide a tripping signal and a supervisory signal to the secondary winding. And a trip sensor associated with the secondary winding. 6. The station of claim 5 wherein the detector consists of a reedlay with a laylay coil, the coils connected in series across the secondary winding. 7. Station according to claim 5 or 6, characterized in that the pulse transformer is operating in flyback mode. 8. Station according to any one of the preceding claims, wherein the intertrip signal is at a voltage of 120 VDC and the supervisory signal is at a voltage of 20 DVC. 8. A station as claimed in any preceding claim, wherein the intertrip signal is at a voltage of 120 VDC and the supervisory signal is at a voltage of 2 VDC. 10. The method according to any one of claims 1 to 9, wherein the monitoring signal detector is a detector for comparing the signal from the output device with the existing signal to generate an alarm signal when the signal from the output device is lower than the level of the reference signal. Station. 2. The apparatus of claim 1, wherein the output device is comprised of a DC-to-DC converter with a pulse width modulator, the buffer device is comprised of a pulse transformer with a primary winding and a secondary winding, and the output from the pulse width modulator is 1. Used to switch the current flowing in the secondary winding, two or more sets of timing components are associated with the modulator, one set of timing components causing the modulator to generate an output, allowing the transformer to provide a supervisory signal and another set of timing The component is associated with the modulator and, in response to the intertrip transmitter, causes the modulator to generate an output, disabling the one-sheet timing component that causes the transformer to provide an inter-trip signal, and the detector Which consists of two lead relays with tripping, the trip relay has a normally open contact, When the relay has a normally open contact, the alarm relay in series with the supervisor relay has one or more normally closed contacts, and when the supervisor relay is activated, the alarm relay is activated to generate an alarm signal. The trip signal transmission device constitutes a relay having one or more normally open contacts, the transmission relay is in series with the second set of components, and the control relay provides a control relay to provide a trip control function. An inter trip station, characterized in that it is in series with a trip relay relay contact. Inter trip station as described with reference to the accompanying drawings. Two-way communication is possible between stations, and one station can act as a master station and provide its own inter-trip and supervisory signals, and one or more stations away, ie slave stations, acting as slave stations. 13. An inter trip system having at least two stations according to claims 1 to 12, which can provide a signal and a supervisory signal, wherein the slave supervisory signal is lower than the level of the master supervisory signal. Inter-trip system as described in the accompanying drawings. A core, a primary winding wound on the primary former and a secondary winding wound on the secondary former, the windings and the former being arranged coaxially with each other to extend around a common part of the core and between the windings Pulse transformer characterized by good coupling and electrical isolation. The transformer according to claim 15, wherein a tracking flaw and a ridge are formed in one of the formers. 17. The transformer of claim 16, wherein the secondary former has a cylindrical portion and end flanges to which the windings are wound, and the tracking grooves and ridges form end flanges. 18. The transformer according to any one of claims 15 to 17, wherein the core has a gap between them to enable the transformer to operate in flyback mode. 19. The arm according to any one of claims 15 to 18, wherein the core has a core arm, a winding is installed around the core arm, the core has another pair of core arms, and one arm of the pair of arms. A transformer, wherein the silver winding is provided on either side of the arm. 18. The transformer of claim 17, wherein the primary former has a portion receiving the primary winding on which the primary winding is wound, the portion receiving the primary winding being received into the secondary former. 21. The transformer of claim 20, wherein the primary former has end flanges to limit the extent to which the portion receiving the primary winding protrudes from the secondary former. Transformer as described with reference to figures 4, 6a and 6b of the accompanying drawings. ※ Note: The disclosure is based on the initial application.
