< < < --Technical Parameters of Inspection Cabinet<, three aspects will be focused on and dedicated to Industrial enterprises and social users provide novel, safe and reliable products and solutions as well as related services.
< The principle of the fire control cabinet is to receive the alarm signal of the fire alarm equipment and link other related fire equipment according to the received fire alarm signal.
< In addition, a battery pack is required to be placed at the bottom of the chassis and takes up space, so a total of space is actually required.
< Dual power supply is an automatic transfer switch that integrates switching and logic control without the need for an external controller to truly realize electromechanical integration. It has functions such as voltage detection, frequency detection, communication interface, electrical, and mechanical interlocking to achieve automatic, Electric remote, emergency manual control. The operation is performed by the logic control board using various logic commands to manage the operation of the motor and gearbox to realize the motor driving the switch, the spring energy storage is instantly released, the acceleration mechanism quickly connects and breaks the circuit or performs circuit conversion, and achieves safe isolation through clearly visible states. Greatly improve the electrical performance and mechanical performance. The switch is suitable for automatic conversion of the main power supply and backup power supply of the power supply system or automatic conversion and safety isolation of two load devices. The transfer switch is mainly used for one main and one backup or mutual backup power supply switching system in the power distribution or motor network with AC rated voltage, DC rated voltage and rated current, and load switching between mains and generator sets. At the same time, it can be used for infrequently connecting and breaking circuits and line isolation. The products are widely used in power transmission and distribution systems and automation systems in fire protection, hospitals, banks, high-rise buildings and other important power supply places where power outages are not allowed. The automatic transfer switch complies with: - "Low-voltage switchgear and control equipment Part 2: Switches, isolators, isolating switches and fuse combinations". - "Low-voltage switchgear and control equipment with multiple functions."
< When the motor is lightly loaded, the soft starter can [--inspection cabinet] reduce the terminal voltage and improve the motor power factor to achieve light load energy saving.
< Many electrical components such as time relays and time relays make control simpler and more reliable. Due to the use of programmable controllers
<, it can be seen that the consumption level of Chinese consumers has greatly improved and the proportion of price has decreased. People pay more attention to the quality of the product itself, functional features, user experience and other needs.
< The inspection cabinet operates according to the cycle and time set by the touch screen, and can also inspect individual water pumps in manual mode.
< . Whether the procedures for making fire are handled in accordance with the regulations. Whether the welder's operation complies with the operating specifications and meets the eight no's, four musts, and one clear requirements.
< The back panel can be easily installed and fixed with screws, and the cabinet door can be replaced.
< < --Functional features of the inspection cabinet<. The main circuit of the water pump control cabinet is composed of isolation circuit, short circuit protection, overload (backup) protection circuit, start and stop (variable speed) control appliances, and thermal relay [--Inspection Cabinet 】And distribution wires and cables, etc.
< To achieve the purpose of maintaining troops for thousands of days and using them for a short period of time, fire water pumps must be equipped with automatic inspection devices. The inspection is a low-frequency inspection. During the inspection, the motor speed is rpm
<. Principles for selecting the variable frequency water pump control cabinet system
<. The status and operation process of the water pump during operation are set and displayed on the color touch screen. .
<. During automatic inspection, low-frequency AC power is used to drive the fire pumps one by one so that each fire pump operates at a low speed (the rotation speed is not greater than /) and the rotation time is not less than.
< , SMS alarm function for equipment failure (optional).
< , can detect power supply under-voltage, over-voltage, under-current, over-current, and phase loss.
<, focusing on the fire protection industry's demand for automatic inspection control products based on a series of core intellectual property rights it has obtained
<, the type of data, fault records and the time of occurrence are clearly displayed and easy to understand at a glance< br/>< The intelligent inspection controller outputs inspection instructions to inspect the main circuit contactors one by one. The inspection return signal is taken from the main auxiliary contact of the contactor.
< --Working Principle of Inspection Cabinet<. Fire maintenance personnel [--Inspection Cabinet] can be quickly dispatched to the local area to turn on the key switch and force the landing.
<, fire control room hard-wired start (passive normally open point)
<, forced start (emergency start) device.
< The installation method shall be explained by the bidder. The floor-standing control cabinet is installed on corrosion-resistant channel steel, which is firmly connected to the floor with bolts.
< . Single pump inspection time: minutes (can be set according to user requirements)
< . When automatic switching is not required, the switch can be converted to manual switching to select the main and backup pumps. This type has the function of automatic switching of the backup pump.
< The controller will record the faulty branch number and fault type and issue an audible and visual alarm. At the same time, the upload of faults is completed
<. The human-machine interface adopts a Chinese menu and has a data memory function that can memorize transient parameters during faults
< and can also be automatically put into operation according to pressure changes. The inspection control cabinet is suitable for various types of fire water supply, which can improve the reliability of fire water supply and meet the requirements of fire protection standards.
< , With the continuous improvement and development of the construction industry, Yueqing Huixian Electric Technology Co., Ltd. has launched fire inspection cabinets in accordance with national standards and using the latest achievements in control technology.
