No contact long life soft start energy-saving distribution box

Abstract

The invention relates to a novel distribution box characterized by no contact, extended service life, soft starting and energy saving. The invention is applicable under the bad environment such as kindle-prone, explosion-prone and dust. As an innovative and replaceable product of distribution box, the invention changes the present structure module of the mechanical distribution box without using any ac contactor, and changes the distribution structure which can only control the connection or disconnection of the source into the intelligent automatic structure according to the loading requirement. The invention has no spark, presents safety and reliability, and prolongs the service life greatly. The structure is divided into the following four parts: a series connected thyristor main circuit, a center controlling circuit, a multifunction protection circuit and an eliminating harmonic instantaneous flow purification circuit. The invention has a multifunction protection system for protecting the safety of the devices. The invention also has an advanced soft starting system which greatly reduces current and voltage and completely removes the hulking antihypertensive starting equipment totally to save investment. The invention has a quick inspection and central processing system which stochastically controls the electricity consumption quantity and increases the power factor to save electricity. Furthermore, the invention has the advantages of small volume, light weight, automatic and easy operation, steady running and few needs of maintenance .

Description

Technical field: [0001] The invention relates to a power distribution device, in particular to a non-contact, long-life, soft-start, and energy-saving power distribution box. It is a fully automatic new power distribution device of mechatronics. Background technique: [0002] In today's electrical age, power transmission is a huge industrial chain. It is a necessary equipment for the utilization of electrified electric energy, and the quantity is very large. In the past, power distribution equipment used mechanical AC contactors, circuit breakers, and air switches. It is used to control the on and off of the power supply, but it can only play the role of on and off, but can not achieve the control of electric energy, and it is easy to produce arc sparks between the contacts, which will cause ablation damage and the environment is unsafe. Especially for high-power equipment, such as inductive loads such as motors, in order to start smoothly, it is necessary to add a step-down star...

Problems solved by technology

It is used to control the on and off of the power supply, but it can only play the role of on and off, but can not achieve the control function of electric energy, and it is easy to generate arc sparks between the contacts, which will cause ablation damage and the environment is not safe

Especially for high-power equipment, such as inductive loads such as motors, in order to start smoothly, it is necessary to add a step-down start-up unit, such as an autotransformer, Y-△ step-down start, frequency-sensitive resistor step-down start, etc., which is very troublesome, and the equipment bulky
