  MAIN BODY CONSTRUCTION The automatic reclosers are constructed with vacuum interrupters with magnetic actuation mechanism, with solid resin insulation.

Coupled three-phase operation
The reclosers will be bi-directional therefore suitable for forward and reverse current flow.
 
Materials
All materials used in the manufacture of reclosers shall be highly resistant to the corrosion of saline atmospheres.
 
Surface treatment
The ferrous parts shall be of stainless steel for enclosures and cabinets. Corrosion treatment by means of hot dip galvanizing in accordance with ISO ***1 is only permitted for support structures and fastening components.
 
Insulators
The insulators will be of solid dielectric insulation with the cycloaliphatic epoxy resin system or silicone rubber type HTV, Porcelain or EPDM insulators are not allowed.
The creepage distance shall be at least *1 mm/kV. Insulators shall withstand a bending motion of **0 Nm and withstand a suitable torque for the fastening of the conductors.
The insulation material must have a hydrophobic behavior, highly resistant to ozone, oxygen, moisture, pollution and ultraviolet (UV) radiation resistant (according to IEC ****9). No UV coatings or covers are accepted.
 
 
 
Position indicators
Position indicators shall be resistant to aggressive weather conditions, possibly by the adoption of transparent protection, and shall be of such dimensions as to be clearly visible from the base of the pole and in any case at a distance of 8 m.
  CONTROLLER The components of control, protection and remote control must be located in a box treated against corrosion.
The box will be designed to protect electronic circuits from aggressive weather conditions.
The cabinet will be supplied with all the appropriate connectors to ensure connection with the recloser.
The cabinet door must have a secure locking system with an operating handle that allows locking. It must provide a lock with a master key.
 
General characteristics
The cabinet shall be IP *5 class;
Access profiling to control should prevent unauthorized persons from logging in. The access to the configuration of the control must be protected through a minimum of two access keys, one of basic operator and one of engineering or configuration.
A voltage suppressor protection shall be provided for the AC voltage auxiliary on the low voltage side of the potential transformer or auxiliary voltage, suitably sized to protect the control against atmospheric or system surges.
 
Power Supply
The rectifier / back up battery must have sufficient capacity to supply all the control equipment as well as the communications equipment. The voltage is in all cases ******0 VAC, *0/*0 Hz coming from an auxiliary transformer, or directly from the LV network. All auxiliary parts will be supplied at  *4 V DC.
The rectifier shall have the necessary alarms to monitor its correct operation, and the battery shall have sufficient capacity to maintain the operation of the system for *4 hours or to perform at least four cycles of opening / closing operations. The battery shall be included in the delivery.
The battery charger must have some visual indication that informs that the battery is discharged, or has a fault requiring maintenance or change.
 
Local control and protection functions
The recloser control will have the following protection functions:
Phase overcurrent protection (****1),
Residual overcurrent protection (*0N**1N),
Directional overcurrent protection (*7),
Residual directional overcurrent protection (*7N),
Automatic multiple reclosing function (*9)
It must have at least two alternative profiles for the different protection functions including the possibility to program protection curves. Typically one of the profiles will be used in case the power flows from the Source side to the Load side, and the other to the opposite side. The change from one to another setting will be made automatically by the equipment upon detecting change in the direction of power flow or by means of pushs or local switch.
 
 
Other local and remote functions
Activation / deactivation Hot Line Tag mode with led status indicator (switched on if the function is active): Prevents switching operation by remote control and only allows a first protection trip with programmable fast curve, inhibiting reclosing, both automatic, from panel, by connection to computer and even from SCADA. It can only be deactivated in the same way as activated (for example, if activated locally, it can only be deactivated locally and not by SCADA or computer). The indicator light will always remain on while the function is active.
Local indication of:
Position of the switch
Automatic reclosing status
Protection on / off status
Status on / off Hot Line Tag
General Alarms
 
Ability to store operation events. The events to register will be at least:
Oscillographic record of events and stored in Comtrade format
Opening or closing operation
