High-voltage installation I-20M

High-voltage installation I-20M - is designed to test individual means of protecting a person from electric shock with a sinusoidal voltage of 50 Hz. The installation consists of a high-voltage AV-20M apparatus and a prefix BP-2, and is designed for indoor operation. Testing of protective equipment Acceptance and periodic testing of protective equipment shall be carried out periodically in time, established by the requirement of the current legislative norms. In the event of a breakdown, shutdown, discharge or excess of leakage rates, the test product is withdrawn from service or sent for repair. On the means of protection, which passed the tests successfully, a special stamp is set indicating the permissible voltage and the date of the next verification. The main directions of testing of protective equipment: Test of dielectric gloves. The test period for dielectric gloves is once every 6 months. At the same time, the test dates do not depend on whether the product is in operation. Test of dielectric boats and galoshes. The dielectric bot tests are performed by supplying a voltage of 15 kV, and testing dielectric galoshes with a voltage of 3.5 kV for 1 minute. Test of the hand power tool. In operation, only electrical tests of the insulation of the hand tools are carried out. Tests of power tools with single-layer insulation are carried out by applying a voltage of 2 kV for 1 minute. Insulation rod test. The test of operating rods used in operation up to 1000 V is performed by simultaneous supply of a voltage of 2000 V to the working part and to a temporary electrode applied to the insulating part for 5 minutes. Test of voltage indicators. Tests are carried out by applying increased voltage to the working and insulating parts. Features: The installation consists of a high-voltage apparatus AV-20M and a block of attachment BP-2. High functionality of the device is achieved through the use of two measuring channels - which allows you to simultaneously test an alternating voltage and monitor the conduction current of 2 pairs of gloves, or 1 pair of dielectric bot (galoshes). In this case, after the automatic disconnection of the channel due to excess of the conduction current, the others continue to operate independently in the normal mode. Designed for indoor use. The unit is equipped with a built-in timer, which informs about the expiration of the test time by an audible signal. On the front control panel are all controls and displays, as well as measuring instruments. The current is measured by the built-in milliammeter. To ensure greater safety when working with the installation, there is a grounding unit. Due to the design features of the device, accidental contact of high-voltage elements is excluded - therefore, the installation does not require a specially equipped room with a partition and a door with interlocking, only a reliable earthing is sufficient. The kit is highly reliable and easy to operate, and the availability of good access to all the elements of the device provides a special ease of maintenance.
