Description and options of executions
protection of electroinstallations of different function against influence of pulse storm and industrial (switching) retension. Its essence not only in division of object into protective zones and step lowering of the level of dangerous impacts on the sensitive equipment, but also in technically competent placement of devices of protection against the pulse retension (UZIP) in the scheme of electroinstallation, in combination with convenience of installation, operation, service and control of their serviceability.
Considering told above, it is possible to allocate two main types of electroinstallations: these are electroinstallations which already are in operation (including very old, not being exposed reconstruction) both respectively again projected and created electroinstallations. It is absolutely clear that in the first case entering of any changes into the existing scheme becomes very difficult and painful action. In the second case it is competent to place UZIP and chains of their connection becomes possible at a design stage, as has to occur in each case to avoid emergence of difficulties at delivery of electroinstallation in operation and during its further work.
At application of UZIP in electroinstallation of object when dimensional characteristics are not decisive criterion, and at the same time electroinstallation is in process of operation and change in its assembly diagram are undesirable, it is recommended: to establish additional guards of protection against the pulse retension (ShchZIP) of various types (taking into account individual characteristics of object).
