4. Electroprotective means

Electroprotective means - means of protection against action of an electric current, an electric arch and electric fields of industrial frequency.

Electroprotective means share on isolating and special.

Isolating isolating means are necessary to isolate the person from current carrying parts. Share on:

o The cores;

o Additional.

The basic means - means which isolation long time maintains a working pressure of electroinstallation and which allow to perform works on current carrying parts energized.

The basic means is:

In electroinstallation up to 1 кВ:

o Isolating bars;

o Isolating ticks;

o Ticks of electromeasurements;

o Indexes of a pressure;

o Dielectric gloves;

o The tool with an isolating covering;

In electroinstallation above 1 кВ:

o Isolating bars;

o Isolating ticks;

o Current-measuring ticks;

o Indexes of a pressure;

o The adaptation for creation of safe operating conditions at carrying out of tests and measurements in electroinstallation.

Additional means - means, which cannot at the given pressure provide protection against defeat by an electric current, they supplement the cores, and also can serve for protection against a pressure of a touch and a step.

Additional means are:

In electroinstallation up to 1 кв:

o Dielectric footwear (galoshes, boots);

o Dielectric carpets;

o Isolating supports;

o Isolating caps and overlays;

o To cry safety;

o Portable grounding;

In electroinstallation above 1 кВ:

o Dielectric gloves;

o Dielectric footwear (galoshes, boots);

o Dielectric carpets;

o Isolating supports;

o Isolating caps and overlays;

o To cry safety;

o Portable grounding.

5. Protective actions in electroinstallations

Protective actions in electroinstallations include:

1. Selection of workers in electroinstallation (physical examination);

2. Corresponding training working and a passing examinations on qualifying group;

3. The organization of actions of safety:

o Corresponding registration of works in electroinstallation;

o Purpose of works responsible for safe performance;

o Supervision during work;

o The admission to work;

o Translation into other workplace;

o Registration of breaks in work and the termination of work.

4. Technical actions of safety at robots with removal of a pressure, include following operations:

o Switching-off of a pressure from current carrying parts;

o Acceptance of measures interfering erroneous or any inclusion of a pressure, to them concern:

- Removal of fusible inserts of safety locks;

- Blocking switching devices;

- Dismantle of trunks;

o Installation of time fences;

o Grounding the disconnected current carrying parts.
