YNY type insulation monitor

Information description

One, overview:

Insulation monitoring device for monitoring DC is not connected to the insulation resistance of the ground system. When the grid groundinginsulation resistance is lower than the set value insulation monitor alarm relayoutput, the insulation monitoring device can be equipped with display indicates the current system insulation resistance value. The insulation monitor has the advantages of high reliability, good interchangeability and high measuring accuracy and easy to install, widely used in ships, mines etc.. Change theinsulation monitor can not only online real time monitoring system can monitorinsulation resistance, insulation resistance (power system static state).

Two, the main parameters and technical indicators:

1, error:

Measuring range setting range allows the maximum error voltage

0-10M Ω 0.1M Ω M Ω -2.0 ± 5% AC69

0-1 M Ω 0.1M Ω M Ω -1 ± 5% AC69

0-10M Ω 0.1M Ω M Ω -2.0 ± 10% DC69

0-1M Ω 0.1M Ω M Ω -1 ± 10% DC40

2, the response time:

AC power: less than 4S DC power grid: less than 6S

3, the DC power distribution capacitance: less than 3uF

4, the relay output:

A group of switch contacts, contact capacity of AC 250V/5A, DC 30V/5A

5, the relay output:

NO (normally open contact mode), instrument power on state, when the measured value is less than the alarm set value, the relay, the normally open contact by the off state switch to a closed state.

6, the auxiliary power supply: DC 24V ± 10%; AC 220V/380V ± 10%, 50/60Hz (other voltage at

When ordering).
