GCK/GCL1A series low-voltage draw out switchgear

Category:

GCK series motor control center is mainly composed of some combined motor control units and other functional units. These units are installed in a closed metal cabinet in an overlapping manner. Use the horizontal bus set above the cabinet to connect each cabinet together, and the functional units of the same cabinet are connected in parallel on the vertical bus. The cabinet body is divided into four mutually isolated areas, including horizontal bus area, vertical bus area, cable area and equipment installation area. The functional units are installed in their respective chambers. When an accident occurs to any functional unit, it will not affect other units to prevent the accident from expanding.

Product Overview

This product complies with JB/T9661-1999 standard. The product adopts the IP40 protection grade specified in IEC114. When all doors and guard boards are closed, or doors are opened, and functional units are outside the moving position, the product can reach the corresponding protection grade, which can ensure personal safety.

The product is equipped with perfect and reliable grounding system and protection circuit. All functional units can break short circuit current according to specified performance requirements. The incoming line unit has three section protection characteristics. Therefore, it can ensure the reliability of power supply and the safety of equipment and system.

All functional units can be connected with PC line boards (programmable controllers) or microprocessors through interface devices. As the execution units of the automatic control system, functional units and functional combinations of other contents can also be provided according to user needs. This product is applicable to circuits with AC 380V and frequency 50Hz.

Model and its meaning

Main technical performance characteristics

·The main electrical performance complies with the International Electrotechnical Commission | EC standards and the National Electrical Manufacturers Association NEMA standards.

·Each cabinet can use isolation transformer to separate the main circuit and auxiliary circuit, and the operating power supply of the auxiliary circuit is 50Hz, 220V; The signal power supply is 50Hz, 6V.

·The main receiving switch has three sections (instantaneous, short time delay and overload) protection. In order to cooperate with the next level main switch (with instantaneous and overload two section protection), the instantaneous one section is cancelled to avoid skip tripping. It also has automatic switching, non automatic switching and switching devices for selection.

·The horizontal bus has two types: single bus section and non section. When single bus section is adopted, the bus coupler switch also has automatic switching, non automatic switching and switching devices.

·Motor control circuit has short-circuit instantaneous, overload, undervoltage release and open phase protection.

·When the AC contact in each functional unit adopts silent operation, it has energy-saving function. At the same time, when the power supply disappears, it has the characteristics of delayed release (more than 0.3s, less than 0.5s). Therefore, when the power supply can be recovered within 0.3s (reclosing or automatic switching time of standby power supply is less than 0.3s) without installing respective starting relays of motors, the motor can continue to operate.

·The main switch of feeder circuit has instantaneous and overload protection, and leakage protection can be added when users need it

·The main switch of lighting and household appliances has instantaneous, overload and leakage protection. This circuit is especially suitable for power supply of mobile appliances such as electric drills, portable grinders, etc.

·The receiving circuit is equipped with an ammeter, active and reactive watt hour meters. 250A and above The upper feeder circuit can be equipped with or without ammeter and watt hour meter. Other circuits greater than 37kW or 60A are equipped with ammeters.

·In case of accident, lights and alarm devices can be installed.

Conditions of Use

·The ambient air temperature shall not be higher than+40 ° C and not lower than - 5 ° C, and the average temperature within 24 hours shall not be higher than+35 ° C;

·When the relative temperature of the ambient air is+40 ° C, it shall not exceed 50%;

·Higher relative humidity is allowed at lower temperature, such as 90% at+20 ° C.

·However, due to temperature change, moderate condensation may occur occasionally;

·For indoor use, the altitude of the place of use shall not exceed 2000m;

·It shall be installed in a place where there is no violent exposure and impact and where the electrical components are not sufficiently corroded.

Low voltage power capacitor

KD-H dry environment-friendly capacitor adopts advanced German technology and is manufactured in an environment with a hundred level purification level. The element is heated under 10-3 Bar vacuum condition and the protective gas is injected at the same time. In this way, air and moisture can be discharged from the capacitor, thus avoiding electrode oxidation and partial discharge. Through this complex process and strict factory inspection and quality evaluation, it is ensured that the capacitor has excellent stability and long service life. It can be divided into single-phase and three-phase according to different occasions.
