Full Product Information:
The use of CPO / RTN cameras Chambers prefabricated single-sided servicing series CPO / RTN (hereinafter referred to as "CSR") are designed for receiving and distribution of electric energy of alternating three-phase current of industrial frequency 50 Hz for rated voltage 6; 10 kV and currents 630, 1000, 1250А for networks with isolated or compensated neutral for the acquisition of closed switchgears. General information on the design of CPO / RTN cameras CPO is a prefabricated metal structure that can be supplemented with metal panels and partitions. The housing of the CPO chamber is made of galvanized steel sheet. The chamber doors are painted with powder paint RAL 7035. Inside the chamber there is equipment for the main and auxiliary circuits. The CSR cameras, depending on the embedded equipment, are divided into: • CSR with vacuum switch; • CSR with load switch. • CSR with disconnector; • CSR with voltage transformer; • CSR with an auxiliary transformer. CSR cameras with a vacuum switch are manufactured both with the arrangement of the switch on the withdrawable element and on the stationary one. The location of the withdrawable element is in the middle part of the CSR on it, instead of a vacuum switch, both voltage transformers and fuses can be located. As switching devices in CSR with a sliding element, vacuum switches BB / TEL, VS1, VD4, Evolis, SION are used. As for CSR with a stationary vacuum switch, only BB / TEL and BBM-CEP can be used. CSR with a retractable element for increasing the localization ability are separated by metal partitions into compartments: • compartment of busbars; • drawer compartment and connections; • camera control compartment. CSR with a stationary arrangement of the vacuum switch are separated by metal partitions with bushing insulators to the compartments: • busbar and switch compartment; • connection compartment; • camera control compartment. When using CSR sections with a stationary vacuum switch, CSR with a load switch will have the following compartments: • compartment for busbars of the load break switch and sub-switch; • camera control compartment. On the door of the control compartment of the CSR camera there is an active mnemonic diagram. In the CSR chambers with a load switch, a load switch with manual control is installed. As switching devices in CSR with a load switch, the load switches VNPR, NAL, OM, OMV are used. CSR with load switch is divided into compartments: • compartment of busbars; • compartment switch disconnector; • camera control compartment. When using CSR sections with a stationary vacuum switch, CSR with a load switch will have the following compartments: • compartment for busbars of the load break switch and connections; • camera control compartment. In CSR, it is possible to install surge suppressors (surge arresters). The protection and control functions are based on microprocessor devices (BEMN, ALSTOM, ABB, Siemens and others). To measure current, active and reactive electrical energy, it is possible to install digital meters and electric energy meters with digital interfaces RS 232, RS-485. CSR allow the installation of zero-sequence current transformers of a frame type to connect three single-phase cables with the size of the window, ensuring their free planting and fastening. Connecting the control cables from the top.
