Cabinets of relay protection and automation of series SHUAZ-10

Application

A series of cabinets SHUAZ (control cabinet for automation and protection): SHUAZ-10, are designed for the reconstruction of the relay protection and automation compartment of complete switchgears (primarily single-end service assembled chambers and switchgears) with existing electromechanical and electronic relays, obsolete devices. The installation is carried out in the operating cells, PSP cabinets, on the PSP panels on the outgoing lines, sectional switches, input switches with voltage 6-35 kV.

Main functions

  • structure and the list of functions of protection, automation, monitoring and telecontrol, as well as service functions depends on the choice of the version of the microprocessor device MRZS-05L and the wishes of the customer;
  • digital, light (sound) indication (signaling) of controlled parameters, mnemonic diagram of switchgear;
  • heating, cooling, lighting, electricity metering.

Structure

SHUAZ is a complete block - metal structure with relay protection and automation devices mounted on it, ammeter (voltmeter), buttons and control keys, light and indicating signaling devices, control unit and/or switch power supply unit (if necessary), circuit breakers, alarm circuits and automatic dispatching control, accounting circuits (electricity meter). Connection of external circuits is carried out through the assembled row of clamps.

Typical versions SHUAZ

  • SHUAZ-10-L-001 and SHUAZ-10-L-010 - cabinet for current protection, automation and control line, input, section 10 (6) kV;
  • SHUAZ-10-L-121 or SHUAZ-10-L-321 - cabinet for protection of current and voltage, automation and control of the outgoing line 35-10 (6) kV;
  • SHUAZ-10-L-013 and SHUAZ-10-L-033 - current protection cabinet of the feeder cable line 10 (6) kV (with directional earth fault);
  • SHUAZ-35-Т-001 and SHUAZ-35-Т-010 - transformer backup protection cabinet;
  • SHUAZ-10-ТN-121 or SHUAZ-10-ТN-321, SHUAZ-35-ТN-122 or SHUAZ-35-ТN-322 - cabinet of protection and automation for voltage, control and signaling of ТН 35 kV, 10 (6) kV;
  • SHUAZ-10-V-121 or SHUAZ-10-V-321, SHUAZ-35-V-121 or SHUAZ-35-V-321 – cabinet for protection of current and voltage, automation and input control 35-10 (6) kV;
  • SHUAZ-10-S-122 or SHUAZ-10-V-322, SHUAZ-35-S-122 or SHUAZ-35-V-322 - current and voltage protection, automation and control of section 35-10 (6) kV;
  • SHUAZ-10-D-002- protection cabinet for voltage and current, automation and control of engine 10 (6) kV;

SHUAZ differ in design type:

  • Protruding version (for example, for cells with external mounting of KSO type)
  • Recessed version (for example, for cells with internal mounting of KRU type)
  • Opened version (for example, for RPA panels)

Adaptation for various types of switches of a wide range of domestic and foreign manufacturers

  • vacuum;
  • gas-insulated;
  • oil (low-oil)
Adaptation to various types of previously manufactured and modern complete devices
  • KRU series, KRUN series, KSO series, YAKNO series, K series, KN series
  • Advantages of an integrated approach to RPA replacing:

    • SHUAZ will allow quickly and efficiently perform works on the "retrofit" of RPA and related equipment.
    • Simplicity and convenience are accompanied by minimal costs and invariably (guaranteed) quality result.
    • The supply of relay equipment from one supplier simplifies the delivery system and relieves the burden on the buyer's logistics;
    • Optimum dimensions are made in accordance with the type of complete switchgear of service personnel;
    • Individual approach tailored to the specifics of the customer;
    • High quality is determined by high-quality components and experience in performing special operations;
    • The commissioning speed is ensured by a preliminary design and a holistic study;
    • Low cost and flexible system of payment from the manufacturer;
    • Technical support for the entire service life; Warranty and after-sales service;
    The final version of the SHUAZ configuration is determined when placing an order. The order is executed according to the customer documentation (questionnaire and order card). The final schemes and specifications are agreed with the customer.
