SF6 High Voltage Circuit Switchers

Product Overview

Siemens Type CPV2 Circuit Switcher is ideal for applications that do not require reclosing. The CPV2 model provides space-saving protection at an economical cost. Operation of the CPV2 is controlled by a FA2 Spring Operator, which is similar to the operating mechanism used in the SPS2 Circuit Breaker.There are several reasons to specify and install the CPV2 Circuit Switcher: excellent design, robust construction, simple installation, minimal maintenance, and low installed cost.The Siemens Type CPV2 Circuit Switcher device can switch and protect transformers, lines, cables, shunt capacitor banks, and shunt reactors. It also provides a low cost medium fault interrupting device. It has a consistent and fast operating time of 3 cycles with a high interrupting capability of up to 40 kA.

Gas Monitoring

Each pole unit is equipped with a manifold which incorporates a fill valve, a pressure gauge and rupture disc. This manifold is located at the lower end of the pole unit, connected to the cover assembly by a union coupling. The coupling allows the pressure gauge to be rotated by the user to provide the most satisfactory view from the ground. The pressure gauge has a color coded face for ease of reading from a distance. A label showing a picture of the gauge and an operating pressure range versus ambient temperature is located on the door of the control cabinet.

Siemens Exclusive!

As an option, the Siemens Type CPV2 Circuit Switcher can be equipped with a temperature compensated pressure switch to automatically monitor the status of the SF6 gas in the pole units. This switch with gauge is located inside the control cabinet, and has two sets of contacts. One set of contacts provides an alarm indication when the gas pressure approaches within 5 psi of the lockout value. The other set prevents operation if gas pressure falls to a level at which current interruption is not assured. The temperature compensating feature of the switch avoids alarms and lockouts due to normal pressure variations associated with ambient temperature changes.
