Switch box application

Switch box Appication

Manageable, when circuit malfunction happened, it is helpful for maintenance.
Switch box and distribution cabinets, switch cabinets, distribution box, distribution panel, switch, instrument equipment such as concentrated installation of complete sets of equipment. Commonly used two kinds of distribution box with wooden and iron plate system, usually electricity iron with more, and other useful flame retardant materials.
Appications of Switch box: of course, is convenient to stop, sending, have the effect of measurement and judgment stops, either.
When install, pay attention there to be good grounding.

Switch box

Switch box also called power distribution cabinet, switchboard, distribution box, is focused, switching, allocation of power equipment.
Switch box is generlly composed of cabinet, switch (circuit breaker), protection device, monitoring device, electric energy meter, and other secondary components. Installed in power plants, substations and power consumption is bigger power customers.
According to the current, it can be divided into ac, dc switch box. According to the voltage can be divided into the lighting switch box and power switch box, or high voltage switchboard and low voltage switchboard.

Control switch panel double-color injection mould design

This paper introduces the control wall switch socket panel design method of two-color injection mould. Plastic parts with one module and two cavities, balance type 4 runner injection molding solution, solves the plastic parts rely on only 0.3 mm thick sheet connection lead to mold molding difficult problems; Choose their own planar rotating turntable transposition mechanism of P type double color injection molding machine, can simplify the structure of two-color injection mould design; The sprue coagulation material and plastic parts can automatically separate runner gating system, and two kinds of color plastic push rod launch institutions were set up, implement the first color only remove the sprue injection coagulation material and plastic parts not stripping, the second color sprue injection coagulation material with the plastic parts and mold release action request. In addition, the dynamic and fixed mode between cone precision positioning lock, dynamic and fixed mould set piece corner set fine positioning lock and the mould clamping precision is improved, and to establish the overall stiffness of eight root sticks to strengthen the mold.

Good development prospect of Circuit breaker

Circuit breaker classified into residual current circuit breaker and molded case. Circuit breaker has small volume, light weight, suitable for frequent operation, arcing without maintenance, the advantages of wide use in power distribution system.
Residual current circuit breaker features:
(1) arc time is short, and has nothing to do with the switch current size, usually only half cycle.
(2) the contactor from small, 10 kv vacuum circuit breaker contact only from about 10mm, long life of circuit breaker.
(3) after the arc contact gap medium fast recovery and split off area near fault performance is better.
(4) due to unclog the wear is smaller when the breaking current, open circuit for 30 to 50 times full capacity, rated current open circuit above 5000 times, the noise is small suitable for frequent operation.
(5) applies to open circuit of capacitive load current.
(6) Small volume, light weight.
Berise System Integration Co., Ltd. Company main products have CE, CB, TUV, BS, SAA, WATERMARK, UL, CSA, UPC, NSF, and many other certification. Circuit breaker technical standards in our country recent years obtained the very good development. Products from several kinds of models in the past few to dozens of multiple types, varieties, rated current 5000A, switch socket circuit breaker has good prospects for development in the electric power development.
