Product features
1, PGL (1/2) ac low voltage distribution panel, can take the place of BSL series product, the product structure design is reasonable, the circuit configuration of safety, "prevention performance is good, better than the old product has high breaking capacity, good thermal stability, safe and reliable operation, etc and auxiliary circuit scheme corresponding to the chestnut and the main circuit, each main circuit solutions corresponding to one or several auxiliary circuit, so the user can be in the selection of main circuit, can be easily chosen from the corresponding auxiliary circuit scheme of electric schematic diagram.
2, simplified the main circuit scheme, cancelled the multiloop small motor control scheme, and a main circuit scheme more reasonable, what makes this product as a power in the power distribution system, power distribution, lighting, small motor multi-loop control scheme, suggested to select power box series products.
3, the product size screen to find 400, 600, 800, 1 000 mm four, each screen can be used as an independent unit, and to screen for unit combined into various solutions, convenient for the user
The combination of selection, and reach the required solutions.
Product of electrical parameters
1, products insulation voltage: ~ 500 v.
Communication: 2, main circuit rated voltage 380 v.
3, auxiliary circuit of rated working voltage of ac 220 v, 220 v, dc 110 v, 220 v.
4, PGLl type products, the breaking capacity of 1 5 ka (RMS).
PGL - 2 new products, and the breaking capacity of 30 ka (RMS).
Structural characteristics of
This product is installed indoor use, have open double low voltage power distribution equipment maintenance.
The basic structure of the steel plate and Angle steel welded together, before the screen door.Screen positive above can open the dashboard, can be installed, indicating meter with partition between tied for installation of the screen, thus reducing the expansion due to fault the possibility of accident, the terminal screen can add protection board, mistress line installation and insulation box above after screen frame, above the bus equipped with protective cover, to prevent the falling metal objects above main bus-bar malignant accident of the short circuit.
This product has a good grounding continuity, the main spot welding on the bottom of the skeleton, that will compose a complete grounding protection circuit, the reliability of this ground fault protection circuit, has greatly strengthened the ability of product to prevent electric shock.
The neutral bus set up on the screen below the insulator.
Installation and use of plant products
1, the product through the transportation after arriving at the place of receipt, first of all, should check whether the packaging is intact.If found the problem, immediate notice must be given to the relevant departments to find the original garden.Is not installed immediately
Products.According to the regulation of normal conditions of use, the product stored in appropriate places.
2, the installation of the product, should according to figure 2, with the basis of channel steel and screw, Bai Bei by the user.
3, the installation of the product should be in accordance with the manufacturer to supply the drawings, the mistress of the packaging line connected.Busbar lap surface should be clean first, neutral vaseline oil, then use screw fastening namely
Can be.
4, when the mistress line two insulating frame spacing is 1000 mm, in between the mistress of the insulation box line need to add support insulator, to improve the dynamic stability of mistress line strength.
5, the product after installation or maintenance, in operation shall, first of all, the following inspection and test of the project.
A, look for peeling paint film, whether clean inside the screen;
B, flexible manipulator is should not be stuck or operating force is too large;
C, the main electrical on-off is reliable and accurate;
D, electrical auxiliary contacts can break is reliable and accurate;
E, instrument and transformer variable ratio and polarity is correct;
F, busbar connections are in good condition, its support insulator, whether the installation is firm and reliable clamping piece and accessories;
G, protection appliances setting value is in accordance with the requirements of fuse molten core specification is correct;
H, auxiliary contacts whether accord with the requirement of the electrical schematic diagram of the circuit;
I, protective earthing system meets the technical requirements, meter and relay action is accurate;
J, 500 v shaking table was used to measure insulation resistance shall be not less than 0.5 M ῼ.
6, matters needing attention in the operation of the product:
A, this product is not wall installation ac low voltage distribution equipment, screen for maintenance and operation of channel, positive, open the door at the operation and maintenance;
B, the product at the back of the channel and the front door, there must be after the inspection qualified professional personnel, maintenance personnel, or according to the prescribed procedures approved by the people, shall not enter the channel or open the door lock (or gate
Buckle) for maintenance and operation.
