VOLTAGE INDICATOR SNIK –M 50 V – 35 kV
Категория: Инж. тех. м. и а. | Новость от: Admin | 27-12-2005

Voltage Indicator is supporting equipment for the staff protection during the work on voltage power lines within 50 V- 35KV.

In comparison with operating analogue equipment, the device has higher sensibility that allows us to divide the range of response into three discrete levels.

The 1-st level – the equipment is operated as a usual current selector.

The 2-no level – is opened as free of contact indicator of high voltage.

The 3-rd level – maximum response

The voltage within 100-220 V and more can be revealed in wires at a big distance. Within this range the equipment is operated as a selector of phases in flats.

The Description of the Equipment

The equipment is shown on the right. There are four switches on the front panel of the equipment. Ï1- is for switching on; Ï2- is for switching of the sound signal during indication; Ï2 is for response reduction – level 2. And Ï4 – is for response reduction – level 1 (usual current selection).

Charging for battery is located from its front, charging socket – for charger connection

Light indicator is for display, when the voltage is reached the requested level in prod aerial. The regime of usual current selector contact to the wires is assumed having the voltage till 380 V. Contact with the wires is absolutely eliminated the voltage of which is more then 500 V. It may cause the damage of the equipment.

Set for Delivery

SNIK-m (with accumulators) - 1

Charger - 1

Passport - 1

Case - 1

The Equipment is supplied with power by 4 nickel- cadmium cells. In waiting regime the equipment is continuously operated approximately within 30 hours. Then it should be charged.

Operation Method

Equipment is switched on by switching Ï1. At the same time battery level is checked, within a few seconds the battery voltage is displayed by needle indicator. It must be in the middle of the red area of the indicator scale. Otherwise the equipment should be charged. The light indicator is simultaneously illuminated above the equipment and the audio signal is heard. It shows that the equipment is in normal state. If Ï3, Ï4 aren’t switched on the indicator response is maximum. It is easy to find out the wires of the voltage 220 V at a distance being equal to 1 meter (to reveal concealed wires in flats).

Within this range electric wires can be easily revealed inside the walls by needle indicator. When passing over the wires the needle shows maximum radiation. Break of wires can be found. Such precise measuring is not provided by similar equipment, which are free of the needle indicator.

During field works within this range at the distance more than 25-30 m the equipment shows the existence of the voltage on high-voltage power lines. According to the level of indication of the needle equipment its phase lack can be revealed by free-contact method, when passing under the wires.

Level 2- switcher Ï3 is in switching state. Equipment is operated similar to active indicators, which are free of contacts.

At the distance of 2-5 cm from low-voltage power lines (220 V) the light indicator is illuminated, audio-signal is heard the needle shows the existence of the voltage.

The features of this range are in the following: which detector is coming near to closed cables the phase is easily found out inside the cables, without direct contact with wires in accordance with maximum of the needle indicator.

During the work at high-voltage transformer substations the staff can easily move in the room having such kind of indicator. He must know the indicator is operated while approaching high-voltage lines at the distance less than 1-2 meters, warning the danger.

Within this range the equipment is complied with indicators (CNIK – 6-10 KV).

Level 1- switcher Ï4 is turned on. Equipment is operated as usual current selector. When the prod is touched to power line of 110 V- 220V, indicator is operated, If the wire is phasic, the needle of the indicator is, the needle of the indicator is deflected to the scale maximum (220 V). But if the voltage is less than 220 V the deflection accordingly will be less, that is, the voltage of lines can be simultaneously measured. At the same time the light indicator is illuminated and audio signal is heard. When the prod is touched to neutral wire or grounding and if the ground quality or neutral wire is higher, the light indicator will be illuminated instantly and audio signal will be heard. Then the equipment stops the operation. The needle indicator shows zero.

But if there is a residual voltage in neutral wire or in the grounding the light indicator and audio signal will be continuously on operation and the needle will show zero.

If the residual voltage is comparatively higher (5-50V) needle indicator is also operated.
