Description

one

The invention relates to equipment for the automation of power systems and can be used to register: power supply interruptions on the elements of the power supply systems for all purposes.

Devices are known for recording operating time and downtime of units and machines f which contain an element of time and cabinets for visually reading 1.

The disadvantage of the device; is the difficulty of applying it to electrical network conditions due to the presence of recording elements,

Closest to the present invention is a device containing a delay unit, the output of which is connected to the input of the counter of the number of breaks, and the input to the controlled object to which the common counter is connected. The step finder is connected via the relay contacts to the motor time relay 2.

The disadvantage of this device is a large number of elements and low accuracy.

The purpose of the invention is to simplify the device and increase its reliability.

This is achieved by the fact that a device containing a delay unit, the output of which is connected to the input of the count of breaks, and the input to

the monitored object to which the common counter is connected, a clock mechanism, a control unit, a winding motor, a clock fixation unit are introduced

set duration and adder. The clock mechanism is connected to the output of the control unit, to the output of the winding motor of the clock mechanism, to the input of the adder and to

one of the inputs of the block of fixation of breaks of a prescribed duration, the other input of which is combined with the inputs of the control unit and the winding motor of the clock mechanism and connected to the object being monitored.

The drawing shows the block diagram of the recorder.

The device contains tires of the object under control 1, an electric motor 2 for winding the clock mechanism, a clock mechanism 3, a block 4 for fixing breaks of a prescribed duration

a control unit 5 containing a clockwork electromagnet 6, a signal support unit 11, a counter of the 8th number of breaks, an ordinary counter 9 and a vacuum device 10. The device operates as follows; When the device is connected to the tires of the object to be monitored 1., the electric motor 2 turns on the spring of the clock mechanism 3. When the voltage on the monitored object 1 disappears, the control unit 5 simultaneously operates with the electromagnet 6 of the clock mechanism, the electromagnet of the unit 4 fixing breaks of the set duration and total counter 9, the countdown of the delay time by the adder begins. The electromagnet of block 4 includes a clutch (not shown in the drawing) connecting the clock mechanism 3 with the setting sector of the interruption duration of block 4 (not shown in the drawing), and the countdown of the interruption time of the set duration begins. Two seconds after the voltage disappears on ishna 1, by means of the signal delay unit 7, the counter 8 of the breaks is triggered. If during the delay time the break is eliminated, the counter 8 does not work. After the set time has elapsed on. sector block 4 (1-10 hours), the latter is triggered. At the end of the break, a voltage appears on the tires 1 and the electromagnet 6 stops the clock mechanism 3, and the electromagnet of the unit 4 turns off the clutch and returns the sector for setting breaks of a given duration to its original position. If the break is less than the set duration, block 4 does not work and this break is not fixed, the duration of the next break by block 4 is counted from zero. The electric motor 2, when necessary, carries out the winding of the spring of the clock mechanism 3. A single spring reserve of the clock mechanism is 48 hours, it is quite enough to fix almost all interruptions of power supply. The next interruption of power supply leads to a similar operation of the hysterator, and its duration is added to the already fixed the duration of the previous break by the adder 10, the remaining nodes work in a similar way. The total time of the breaks is counted on the disk of the sum of the mat 10 with a scale of 24 hours and a division of 15 minutes, the number of days is recorded by a counter of the number of revolutions of the disk. The use of the device in electrical networks allows one to obtain information at a low cost for truel and p), not the first, for calculating the reliability indicators of the power supply system-j during their operation, design and reconstruction. The information obtained with the help of the device is distinguished by substantial accuracy as compared with information obtained indirectly (for example, from the logs of the operational documentation of enterprises). From the difference in the readings of the total number of breaks and steady breaks, the number of operation of the devices is determined, therefore it is possible to distinguish the number of emergency and planned outages. The presence of a block for fixing breaks of a prescribed duration allows fixing breaks whose duration exceeds the permissible production technology dependent on the monitored element of the power supply system, or causing increased damage, etc. The device is practically maintenance free, easy to set up. No additional power sources and devices are required for its use. The device is tested in a valid electrical networks.
