• LYD103-T 6.6kV Live Monitor VPIS Voltage Presence Indicator

  This product is used to provide a switchgear equipment circuit voltage information at the installation status to the operator. As a result of its internal circuitry of low-power light-emitting element, which makes low power consumption, more stable performance and higher reliability. For the user test double-loop phase conveniently, indicator(recommend type) panel setting the end of the test phase, meanwhile the frame of indicator (recommend type) shell adopts front end removable. And the user can change the indicator without opening the indicator shell.

  Widely used for indoor 7.2,12,24,40.5kV, frequency of 50Hz high voltage electrical equipment, and supporting the use of the voltage sensor, it can reflect the high voltage live situation, and voltage sensor support, but also to improve the anti-error performance ancillary products.

• The main function

  1、Ground and short-circuit fault indication

  Ground and short circuit fault indicator is through the sensor detection circuit to circuit grounding or short circuit fault occurs,

  the value of the current reach or exceed the set alarm sensor current, short circuit sensor signal instantaneous alarm, through

  the optical fiber transmission to the host , the host receives the signal, a corresponding alarm indication signal;

  2、High pressure charged instructions

  Sensors or cable casing extract signals and indicator active connections, through the long life of the

  light-emitting element to realize high-pressure electric luminous indicator.

  3、Locking function

  Host access to extract the signal. Through the op-amp, by the signal processing and electromagnetic lock

  connection to realize mechanical locking function.

  4、 High pressure and electric examination

  Nuclear phase inverter with test electricity through the high-pressure core hole on the front panel to

  check two high voltage electric cabinet put oneself in another’s position of phase and check electrical operation;

  5、Low pressure alarm indication:

  Fault indicator part on battery power, when the battery voltage is lower than the normal operating voltage,

  will produce low voltage alarm indication signal, to remind staff to replace batteries, ensure timely and accurately

  reflect the high voltage line fault condition.

  6、 Automatic reset:

  After the alarm signal indicator, if no manual reset, after the setting time, indicator can be reset automatically.

  “Gear” optional, reset time (8 seconds, 6 h, 12 h, 24 h, 48 h, default reset time of 12 h).

  7、 Manual reset

  When after the alarm indicator, indicator that is triggered by main board on the front panel “reset / test” button to cancel the alarm.

  8、Remote reset operation

  Indicator to generate the corresponding alarm indication signal, alarm signal can be output far eastone .

  Reset signal indicator can also accept the distance, the indicator for the remote reset operation.

  9、Automatic test

  By host panel reset / test button panel L1, L2, L3 and L4 indicator light flashes instructions,

  flashing automatically reset after nine times, at the same time can also be manually reset,

  two adjacent self-checking operating time is 2 to 5 seconds.
