Retrofit of medium voltage panels: features and benefits modernization Bashny.Net

Nine million eight thousand one hundred nine

Complete switchgears and camera of unilateral service slowly becoming obsolete. Components lose power and become irrelevant. Change things perhaps. This requires a retrofit of medium voltage panels, turning to the professionals.

What is the procedure

Retrofit – partial upgrading of the system, equipment which is obsolete or has fallen into disrepair. It is used for extension of the rock operation of individual cells. In this case, the replacement can be high voltage switches, microprocessor relays, meters, gauges, transformers, contacts.

Professional upgrade allows you to increase the electrical security camera, improve dielectric properties, reduce the frequency of maintenance personnel, to eliminate the risk of incorrect operations, etc.
The replacement of components after a thorough examination of the camera, detection of faults, making the list obsolete parts. Today for these purposes, used ultra-fast methods of gathering information – a three-dimensional scanning.

The relevance and characteristics of modernization

Wear parts distribution networks often reaches 70% or more. But not every company has the means for full reconstruction. Reached the wear limit switching devices pose a threat to employees and equipment. Ongoing maintenance operations do not solve the problem, but lead to useless expenses.

Retrofit or upgrading of cells CSR is the optimal program that aimed at replacing the most vulnerable and the responsible component. At the same time remain the case, insulation, tires and other components that are able to work long time without losing their original characteristics. Optionally, in the process of execution of the specified type is a schema change protection, automation, etc.

Usually a set of activities defined group of worn-out components. Last there are four types:

• movable components, including circuit breakers, disconnectors, earthing devices, roll-out sites, stanochnye mechanisms;
• stationary components, and in particular housing, insulation, transformers, tires;
• switching the type of secondary protection relays and arc type, means of measurement sensors;
• switching devices – contactors and circuit breakers.

The main advantage of the partial modernization of the cells is an economic issue. The amount of savings can be up to 50-70%. But there are other positive aspects. This is the minimum time costs, the possibility of reducing the duration of downtime (disable requires only one connection). With the right approach, use of quality components to the lifetime of CSR can be increased at least up to thirty years.
