Intelligent low-voltage electrical appliances shall meet the requirements of high performance, reliable work, small product size, combined design, communication, energy saving and environmental protection, and shall have such functions as protection, monitoring, communication, self-diagnosis and display. Necessary.
1, low-voltage electrical basic intelligent technology
At present, the basic meanings of intelligent low-voltage electrical appliances mainly include the following functions: complete functions of protection and control, self-diagnosis and alarm of electrical parameter measurement, external fault detection, alarm and switch internal fault diagnosis, system operation status monitoring, Or some of them). To this end, the following technologies need to be further studied.
1) All kinds of low-voltage electrical appliances according to their low-voltage power distribution, control system status and role of what should have intelligent functions? How to achieve these functions?
2) intelligent low-voltage electrical standards research and development; intelligent functional test equipment, test methods.
3) Intelligent low-voltage electrical integration technology research; a variety of intelligent electrical integration, different low-voltage electrical appliances intelligent function rounding; a variety of functions overlap each other coordination and cooperation.
4) intelligent low-voltage electrical reliability (including EMC technology) research.
2, intelligent electrical communication technology research
Intelligent low-voltage electrical appliances to give full play to the powerful features, you must rely on low-voltage power distribution and control system network. To this end, made the low voltage electrical communication requirements. In order to meet the network requirements, but also involves a series of technical research.
(1) Networked appliances and systems standardization research.
(2) high, medium and low voltage distribution system seamless connection technology research.
(3) intelligent network system accessory accessories research and development.
(4) Intelligent network system typical solution and overall solution research.
(5) Communication electrical test methods and related testing equipment research and establish the appropriate test base.
3, intelligent distribution system over-current protection of new technologies
When the distribution system abnormal over-current, low-voltage electrical appliances should be promptly disconnected. In order to minimize the failure power outage, low-voltage electrical appliances should be selectively disconnected. Namely, the fault grade protection appliance quickly removes the faulty circuit, and the higher-level protection electrical appliance does not trip, which is especially important for the smart grid.
Smart grid distribution system overcurrent protection should reach what kind of goal?
1) Overcurrent selective protection should cover the entire low-voltage power distribution system, including the terminal power distribution system.
2) Realize selective protection in the whole current range. When the fault current of the lower level reaches the upper momentary current, selective protection can be realized.
3) In a very short period of time to achieve selective protection (control within 200ms).
4) To fundamentally eliminate the system short circuit tripping or upper and lower circuit breaker tripping conditions at the same time. Make sure that the power outage is limited to the minimum.
In order to achieve full range, full current selective protection need to address the following key technology:
(1) The whole range, the whole current selective protection overall solution research
(2) Regional Interlocking Selective Protection Technology Research
(3) universal circuit breaker full current selective protection technology research
(4) Molded case circuit breaker current limiting selective protection technology research
4 smart grid over-voltage protection technology
As a large number of smart grid network, information technology and related equipment, these devices contain a large number of electronic devices, a considerable part of the device itself is electronic. They are susceptible to overvoltage damage from lightning and other switching equipment in the system. In addition, the smart grid will inevitably include distributed new energy systems, these systems are also vulnerable to over-voltage damage, both power generation equipment and control equipment, so smart grid over-voltage protection is particularly important, it involves the following key technologies.
1) Smart grid SPD configuration technology (overall solution).
2) SPD product structure and performance research of smart grid.
3) Smart Grid SPD use safety studies.
4) Smart Grid SPD combination technology research.
QUANTUM Bucket Elevators have successfully been installed in a wide range of applications and capacities. From process equipment, handling a few kg /hr to over 2000 t/hr with a vast range of materials. Whether your application requires a heavy-duty high capacity machine or an industrial process elevator for your factory.
We have a wealth of experience in designing the correct bucket elevator for your application and have a standard range of elevators, which can be specifically designed for, more specialised applications.
Our elevators have conveyed high temperature, high wear, abrasive, large lumpy, sticky non-flowing materials, as well as free flowing powders and granules. We supply a standard range of twin chain and belt elevators single or twin bucket design for high capacity applications such as grain, minerals and ore. The selection of the elevator depends on the material characteristics and IBS will be able to advise you and select the elevator most suited to your material and your application.
• Gravity elevators
• Positive discharge elevators
• Central discharge slow speed elevators
• Centrifugal elevators
Gravity Type Bucket Elevator
Quantum supply gravity discharge elevators and positive discharge elevators, supplied as close bucket discharge type, central discharge type, or Idler wheel discharge.
Generally a slow speed design gravity bucket elevator is primarily installed for elevating large lumpy & abrasive material. Our standard units are usually chain driven, either friction drive or toothed sprocket.
These elevators offer reliability with minimum wear & a positive discharge emptying of the bucket.
Centrifugal Type Bucket Elevator
Quantum standard range of centrifugal elevators are the most common type of elevator installed to most industries supplied in both belt type or chain type depending on material characteristic and the capacity being elevated and in some case the feeding method of the elevator.
Conveying type
• Segmented tooth sprocket chain type, twin chain or single dropped forged link chain
• Friction chain type elevators, European rolled chain
• Belt elevator. Using rubber belt or 100% polyester solid woven belt, nylon and steel woven belt Typical Construction
