China Wholesale Gis High Voltage Supplier – Sivacon 8PT Low Voltage Withdrawable MCC Switchgear – Greenpower

General Introduction

GPS1 type components is for Siemens breakers of low-voltage power distribution equipment, which has circuit breaker technology, fixed-mount technology, withdrawable design technology and plug-in technology. It has safe, reliable, flexible, widely used in the construction industry and industrial technology fields.

The product has the following characteristics:
● Low voltage distribution equipment type-tested (TTA);
● Horizontal bus unified arranged in the top of the switchgear;
● 3-Pole and 4-pole busbar system rated current up to 7400A;
● Rated peak withstand current 1pk can reach 375kA;
● Big depth dimensions of the device compartment, suitable for a variety of installation;
● Device compartment can be divided into different units as the modulus structure;
● The switchgear can be installed on one side, also can be back to back installation;
● Incoming line can be from the top or from the bottom;
● Outgoing cables can be connected from the front or the rear of the cabinet.

GPS1 low-voltage switchgear components containing a total of four designs: Design breaker, fixed-mounted design, plug-in design and withdrawable design.
Breaker design for practice, the current level of bus can be divided into 3200A, 4000A, 7400A, the cable wiring compartment in the side or rear, the circuit breaker can be transferred from the connection position, test position to isolated position. Only breaker in isolated position, the door can be open, this is ensure maximum personal safety.
Fixed-mount cabinet modular structure, which makes the feeder circuits in the cabinet can be any combination. Cabinet installed fixed or insert type molded case circuit breakers(MCCB), fuse type disconnectors, or strip-type disconnectors with fuse, its distribution busbar maximum rated current is 1400A; The protection class of the distribution busbar of the strip fuse cabinet is IP20B, using strips 3NJ6 fuse switch, the device can be replaced without power down the entire cabinet. Power factor compensation cabinet has a choke and non-choke type.
Each drawer withdrawable design has connected position, test position and an isolated position. Drawers up than 125A has a mechanism that can overcome drawer advancing the process of friction. Drawer maximum rated current of 630A, modulus drawer is 100,150,200,300,400,500,600,700mm.
Plug-in type is designed to have a fixed device installed on the slats, plug into the main circuit and auxiliary circuit plug with the slat, main circuit cable outlet to take fixed wiring directly connected to the outlet devices. This design is more economical price.
In order to adapt engineering needs of according to BS standard design, all designed bus system were carried out 3S rated short time withstand current test.

Frame Structure and Enclosure

Load-bearing parts of the skeleton switch cabinet, which is made of steel profiles connected to each other, GPS1 skeleton structure dimensionally accurate and stable. There are two kinds of structure, namely screw connection or welded.
● Profile has 25mm hole distance modulus to meet the needs of various extensions
● Rotating handle spring can reliably prevent inadvertent or accidental leaving the door bounce
● Roof equipped with pressure relief devices

Enclosure
Roof plate
Roof plate is screwed onto the frame, the roof can be lifted without dismantling switchgear, IPX1 or IPX2 type protection class roof will delivery as accessories.

Bottom plate
In order to sealing the SPS1 from the bottom, can be screwed to the framing plurality of steel plates, you can punch holes on the floor for threading the cables. For a higher level of protection requirements, After holing the bottom plate at the site could use regular sealing stuffing for blocking.

Rear plate and Side wall
GPS1switchgear back and sides is made of not chamfered flat steel plate and screws attached to the support structure.

Partition plate
According to internal separation of different forms, for GPS1 switchgear cabinet installation in a row, partition plate is adopted for isolation between the form of the division. Spacer is mounted on the outside of the left frame.

Skeleton Details

Fixed Type Overview and Features

OFF1 uses fixed mounting technology feeder cabinet, can be installed molded case circuit breakers (MCCB), fuse switch disconnectors.
OFF1 fixed outgoing circuits installed by the composition of the modular device compartment and located in the rear of the cable compartment.
Switchgear front is door or plate.
OFF2 the distribution cabinet of feeding outgoing circuits uses fixed mount technology can be installed molded case circuit breaker (MCCB), fuse switch disconnectors.
OFF2 electrical switch of cable feeder circuits is mounted on the mounting plate and connected to vertical distribution bus on the incoming side.
Switchgear front has separate compartment doors, cable connection compartments are in the front as well.
OFF3 feeding-out fixed installation cabinet is composed by a modular device compartment and a cable compartment located in the rear of cabinet.
OFF3 cable feeder circuits electrical switch is mounted on the mounting plate and connected to the vertical distribution bus of the incoming side.
Switchgear front has separate compartment doors.
OFF 4 outgoing circuits fixed installation consists of modular device compartment and a cable compartment located in the front part of the cabinet.
OFF 4 cable feeder circuits electrical switch is mounted on the mounting plate and connected to the vertical distribution bus on the incoming side.
Switchgear front has separate compartment doors.

Draw-out Type Overview

Equipped with an electric motor and feeder circuits of withdrawable switchgear in safe and flexible premise of providing convenient operating, through withdrawable design, enabling quick and easy replacement and adjustment, which means that during the operation, can be Added module compartment and replace or convert.
Features
Main circuit with the movable barrier (breaking in the incoming side and the outlet side) and auxiliary circuits (up to 40-pin + 1 bus connector) of the contact system. Misuse protection mechanism prevents movement in case of contact with the load. In the test position, relative performance of the withdrawable units can be detected in the state of mistakenly load (cold status) status. In this position, we need to feeder the control voltage through the auxiliary contacts. The protection class on the position of test and isolated position is up to IP30.
