3300/01-01-00 Product Description

Product Overview

3300/01-01-00 This is the standard system frame of the Bently 3300 series, serving as the basic load-bearing equipment for the industrial rotating machinery condition monitoring and protection system. This frame adopts an industrial reinforced structure design, with high mechanical strength. It integrates an integrated power bus and signal backplane internally, ensuring reliable electrical connection and a neat layout of the circuits. The product has excellent seismic, dust-proof, and electromagnetic protection capabilities, and can adapt to complex industrial site conditions, supporting continuous operation around the clock. As the physical base and electrical interconnection core of the entire TSI system, it provides standardized installation positions for various functional modules of the same series, while completing centralized power distribution, internal signal transmission, and external line connection, ensuring the coordinated operation of modules such as vibration monitoring, shaft displacement monitoring, and relay output, and is an indispensable basic hardware for building a complete 3300 series monitoring system. Basic Information

This product belongs to the 3300 modular monitoring system. The model clearly indicates the rack specifications, slot configuration and hardware version. The equipment adopts a series of unified size standards, and the slot structure is precisely designed to fully adapt to the 3300 full series plug-in functional modules. It supports rapid insertion, installation and disassembly of modules, making on-site assembly and spare parts replacement very convenient. The entire machine is strictly manufactured in accordance with industrial electrical safety and electromagnetic compatibility standards. The shell structure is sturdy and can withstand slight mechanical impacts, dust intrusion and vibrations generated by equipment operation. It is suitable for conventional application environments such as industrial cabinets, central control rooms, device control rooms, and local cabinets of units. The rack is equipped with an independent power supply circuit and signal transmission backplane. The electrical contacts are reinforced, with stable conductive performance. All external wiring ports are standardized, and wiring, rewiring and line maintenance operations are simple. This equipment is fully compatible with 3300 series power modules, various monitoring modules, alarm output modules, and communication modules. System expansion, modification and upgrade are flexible and convenient.

Function and Positioning

This rack integrates three functions: physical support, power distribution, and signal interaction. At the physical level, it provides fixed slots and limit structures for power modules, vibration monitoring modules, shaft displacement monitoring modules, speed monitoring modules, relay output modules, etc., ensuring that all modules are firmly assembled and effectively counteracting the displacement impact caused by on-site vibrations. At the electrical level, relying on the internal bus system, the power module's output electric energy is evenly distributed to each in-place module, achieving centralized power supply for the entire equipment. At the same time, through the backplane signal lines, a system internal communication channel is established to complete the real-time interaction of monitoring data and alarm instructions between modules. The external part of the rack reserves a dedicated wiring area, enabling the external connection of the system's total power supply, monitoring signals, interlock alarm lines, etc., facilitating connection with on-site industrial control systems, alarm devices and external control circuits. In addition, the rack structure design is convenient for maintenance personnel to check the module contact status and troubleshoot line connection faults. It is mainly applied in scenarios such as overall setup of monitoring systems, centralized power supply, internal signal transmission, and external line connection, providing stable hardware support and electrical link guarantee for the entire unit safety monitoring system.

Core Performance Parameters

The overall mechanical accuracy of the rack is high, and the slot matching is excellent. It can support the long-term repeated insertion and removal of modules. The slot body and electrical contacts are less likely to experience loosening, deformation, or poor contact. The internal power supply bus and signal backplane circuits have low impedance and low power transmission loss. Analog signals and switch signals are transmitted stably without distortion or significant attenuation. The equipment's vibration performance meets the requirements for industrial cabinets and can withstand normal on-site vibrations for a long time. The connection points remain stable throughout the operation. The backplane lines adopt partition isolation and electromagnetic shielding design, effectively shielding electromagnetic interference generated by high-power motors, frequency converters, and high-voltage lines, avoiding cross-interference between power supply circuits and signal circuits. The equipment supports 7×24-hour continuous operation. The internal circuits and metal contacts have strong oxidation resistance and aging resistance, and the long-term operating performance shows no significant degradation. The service life meets the standards for long-term operation of industrial equipment. The insulation performance between each circuit and ground is excellent, effectively avoiding electrical hazards such as leakage and short circuits, enhancing the overall system operation safety. The working temperature and humidity range of the equipment is compatible with conventional industrial indoor and cabinet environments, with a wide temperature and humidity tolerance range, and outstanding environmental adaptability. In terms of system configuration, it must be used in conjunction with the dedicated power module of the 3300 series. At the same time, optional vibration monitoring module, shaft displacement monitoring module, speed monitoring module, relay output module, communication module and other full series of functional units can be selected as needed. The slots can be flexibly arranged according to the on-site monitoring points and alarm logic. The external interfaces of the frame can be connected with industrial power cables, shielded signal cables, interlock control lines, industrial control system connection lines and other external devices. The frame's supporting components and general accessories all adopt the unified specifications of the 3300 series, making spare parts procurement and replacement convenient. Daily installation and debugging, patrol inspection, line maintenance and fault troubleshooting can be completed using conventional industrial electrician tools.

Applicable equipment fields

The product is widely used in power generation, petrochemicals, coal chemical industry, metallurgy, oil and gas extraction, heavy equipment manufacturing and other industrial fields, mainly serving as the carrier frame for the 3300 series unit condition monitoring system. The compatible equipment includes steam turbine generators, gas turbines, centrifugal compressors, large draft fans, flue gas turbines, high-pressure large pump sets, heavy-duty gear sets and other various medium and large-sized rotating mechanical equipment. The equipment is mainly installed in the main control cabinet rooms of power plants, control rooms of chemical plants, power plant power rooms, electrical cabinets of industrial and mining enterprises, local monitoring cabinets of power units, etc., serving as the basic carrier of the entire TSI monitoring and protection system, ensuring the stable assembly and coordinated operation of various monitoring and protection modules, and providing hardware support for the safety control of core power equipment.
