Description

(54) DEVICE FOR INSPECTION OF INSTALLATION CORRECTNESS AND HARVES ISOLATION

. The invention relates to electrical measuring equipment and can be used to monitor installation with,: a check of the electrical strength and insulation resistance of electrical circuits.

Devices are known for checking and registering electrical connections (ES wiring, containing connection and interrogation simulators and black control in the presence of connections 1.

The lack of known devices is the impossibility of monitoring the electrical strength and resistance of the insulation of the circuits.

Known devices for mounting the correctness are known, containing output clamps of a controlled LEA, connected via a junction block with a connection switch, normally closed contacts of the output relays of which are connected to one of the inputs of the insulation control unit via resistors, and directly with the other switch the input of the control unit of the presence of communications, and the switching input - with the control unit of isolation, a switch connected to

The windings of the output relays of the connection switch and the zapsminakdiy block 2. The disadvantage of known devices -

insufficient performance rabotz.

The purpose of the invention is to increase productivity.

To do this, a device for checking the correct installation and insulation

a pinhole containing pin output terminals: rollers of the 1st product, connected via a transfer unit with a connection switch, normally closed contacts of the output relay of which are connected to one of the inputs of the insulation control unit through resistors, and directly with another, a survey switch, the output of which is connected with

the input of the control unit for the presence of connections, and the switching input with the unit, the insulation control, the first switch, the outputs of which are connected to the windings of the output relays of the connection switch, are entered the second switch, the check block of the output relays of the switch switch and the OR element, while the inputs the polling switch is connected to normally close the output relay contacts of the switch under-. kyocheni, the output of the communication presence control unit is connected to the input of the second CC of the switch, the switching input of which is connected to the switch input of the polling switch, the outputs are connected to the windings of the output switch of the switching switch, and the inputs of the state relay check switch of the code switch of the switch of the state of the switch of the switch are connected to the switch input; and to the switching input of the switchboard switchboard, via the OR element, are connected the outputs of the ontrol isolation unit and the checkout unit of the inverse relays of the YD switch. The drawing shows a structural electrical circuit of the device. The device contains a switch 1 connection, made on the relay contact 2 1 -d 2 - h with a self-actuator, on / off alternately bend to 1Mutator 3, To the input m of the switch 1, output terminals 4 of the control unit 4 are connected via an intermediate block 5. The outputs of the switch 1 are connected to the inputs of the insulation control unit b. Resistor 7. 1st 7. Relatively low resistance and provide the transfer of carrying power of the test voltage when testing the electrical strength of the insulation of the product. To the input of the switch 3 is connected the block 8 of the Coytroltyn of the state of the relay 2 1t - 2 p. Outputs of blocks 6 and 8 are connected to the switching input of the switch 3 element 9 OR. The device also includes synchronously operating polling switch 10, switch 11 and communication presence control unit 12. . The paeofaet devices are as follows: -: -. :, -.; ---,;: The test starts by switching switch 3 to the first one. Since the relay 2 and 1 was not turned on, the control unit for monitoring the voltage was turned on and a voltage was applied to the winding of the relay 2. Relay G triggers and gets on the self-operating terminal, and its contacts disconnect the first output of the product 11 4 from the Single input of the insulation control unit and disconnect it to the other input of the insulation control unit. Block 6 is a sequential lack of short circuit, electrical strength and resistance (the isolation of this output is relative to; all other outputs of the product connected together by normally closed relay contacts 2 1 - 2 p. If the insulation is in good condition, block 6 through block 9 switches the switch 5 to the next position. When the switch goes off, the switch 2 2, 2 "1 stays on self-blocking and the second output of the product is connected to the other input of the control terminal blocks. 4. The blackout fixes a short circuit between this output and

.ii; . An output connected to one of the inputs of block 6. According to this signal, the switch 10 is switched on, which in turn connects the resistors 7 1 f 7 n to the block 12 of the control of the presence of connections. When it exits to the third position, block 12 fixes a short distance, since voltage is applied to its input, resulting in a resistor due to current flowing through the jumper between the second and third product outputs from the source in block 6. Signal output from unit 12 through switch 11 Being in the third position, turns on the relay. At the same time, the numbers of the connected outputs of the product are registered automatically or manually. After detecting all the outputs of the product connected to the second output, there is a short circuit signal on the output of block b and there is no automatic test of the electrical strength and insulation resistance of the detected circuit with jumpers with respect to: (the rest Dep m connected to one of the inputs of block 6. If these tests are positive, switch 3 switches to third position, while block 8 detects that relay 2 3 selected in this position is already on, which indicates that the third The signal from the output of block 8 switches switch 3 to the next position without checking the isolation of the third output. The device works in the same way until the switching cycle of switch 3 completes. During the upgrade or after the end of the connection, the addresses of the detected connections are compared. with the circuit of the product and it is concluded that it is in good condition.
