< < < Low-voltage cabinet series --- technical parameters<, When the fire inspection cabinet is inspected, the intelligent inspection controller outputs instructions [Low Voltage Cabinet Series---]
<, which requires high quality of personnel. It is difficult for manual inspection to complete the inspection tasks with quality and quantity.
< The fire inspection cabinet has the function of storing fault content. The corresponding fault type and occurrence time are displayed clearly and easily at a glance.
< , Inspection function: Manual/automatic inspection function (inspection cycle and inspection time can be set arbitrarily) to solve the problem of corrosion and dead pumps of power frequency pumps and improve the reliability of the fire protection system
< , Control loop: Inspection instrument with integrated control loop.
< , The team leader of the safety department is responsible for implementation every day.
< . Each spray main pipe is equipped with water flow indicators and signal valves according to fire protection zones and layers. The signals are all connected to the fire management center alarm valve located on the underground floor.
< , secondary pressure control of flow systems in water plants, pumping stations and petrochemical industries
< , put the inspection manual automatic switch in the stop position to operate and run.
<. In my country's fixed electric fire pump water supply system, one (or more) main pumps are generally used together with one (or more) backup pumps and equipped with a dedicated control cabinet to realize the control of the fire pump. control.
< < Low-voltage cabinet series---Functional features<, Number of control motors: - sets
<. The starting methods of fire pumps are generally divided into two types - the first starting method is in the bus control joint control In mode
<, electrical appliance inspection content: electrical appliance main circuit monitoring, power supply voltage, current, phase loss, insulation resistance, withstand voltage, etc.
< , suitable for the control of various timing or regular intermittent working methods.
< , Although developed countries have advanced technology in pump control, domestic companies started late in the field of automatic inspection and automatic control of water pumps
< , inert gas fire extinguishing equipment, suspended gas fire extinguishing devices, cabinet type Gas fire extinguishing device [low-voltage cabinet series---], oil-immersed transformer draining oil and nitrogen injection fire extinguishing device, aerosol fire extinguishing device), etc.
<, using three-level frequency multiplication to drive the full-bridge inverter design peak ratio High, low switching and filter losses, high inverter efficiency
<, then enter the timer off function setting. At this time, the timer off, the hour bit flashes, press r key to adjust the hour.
< Since the speed is too low to reach the water outlet speed of the pump, it will not increase the claws of the water supply pipe network. All solenoid valves are inactive.
< The main innovation points of the product include: innovative use of single-chip microcomputer technology for automatic inspection equipment, which increases the technological content of automatic inspection equipment.
< < Low-voltage cabinet series --- Working principle<, Horizontal multi-stage multi-outlet series middle outlet can be installed in two ways: vertically upward, horizontal direction
<,: scheduled automatic switching/manual switching
<, with overload, [Low Voltage Cabinet Series---] short circuit, abnormal start-up and fault alarm functions
<, carefully designed and manufactured after years of continuous perfection and optimization in production and application.
< . What special functions does the fire inspection cabinet have?
<. It has a fault alarm power-off flash memory function and a fault storage and recording function that can store multiple fault records to facilitate maintenance personnel's inspection and fault analysis.
< . Operation instructions for emergency broadcast remote control equipment. Please strictly follow the following steps when you need to activate emergency broadcast.
<, It has the function of online detection of electrical circuit insulation, automatic alarm of insulation reduction and recording of fault parameters.
< , Our company has rich experience in preparing the information required for various types of fire protection product certification applications and matters needing attention in factory audits
< , concluded: fire extinguishing system pump station automatic inspection cabinet The production and manufacturing need to comply with - and - standards
