第一段翻译如下
The equipment capacities and power factor according to every workshop, may calculate out entire factory load condition , compensate according to this the power carrying out idle work, the short-circuit current calculation and the design okening the scheme working a telephone switchboard. Work for the safety ensuring that the factory supplies electricity, the instalment succeeds an electricity in responding to in feed system protecting a device , divide the circuit and the transformer two parts, including overcurrent , the overload, speed reaches gas protection absolutely. Be changed into a distribution substation adopt arrester to carry out lightning protection protection , should set up the common ground connection net all around.
第二段翻译如下
The flat surface arrangement being changed into a distribution substation should include high low pressure switchhouse , transformer room , guards' room and foyer, the scheme arranging a scheme to respond to the pattern , capacities according to equipment and passing in and out of gleam of connection carries out rational layout, and considers the ventilation and light selecting measure.

A general machinery introduced distribution system structure and protection system design.
According to the workshop equipment capacity and power factor, the plant can be calculated according to the load conditions, reactive power compensation, the calculation of short-circuit current and the wiring scheme design. In order to ensure the safe operation of power plant should be installed in the power supply system of relay protection device, is divided into two parts and transformer lines, including over-current, overload, fast and gas protection. By lightning distribution on lightning protection, should establish public substationgrounding grip.
Distribution of plane layout should include supply, transformer, high duty and lounge, layout should according to the type of equipment, capacity and take-off wiring schemes, and consider the reasonable layout of ventilated with daylighting measures.

This article describes general distribution system structure and machinery for the protection of system design.
According to various workshop equipment capacity and power factor, load the factory can be calculated according to this situation, reactive compensation, short-circuit current calculations and main wiring design.in order to ensure safe operation of power, should be in power supply system fitted with protective relays, divided into two lines and transformer parts, including overcurrent, overload, instantaneous and gas conservation.substation arrester for anti-Thunder, sizhou should be set up public grounding grids.
substation of layout should include high - voltage distribution transformer room, rooms, room and lounge, layout scheme should be based on the device type, capacity and lockgate wiring layout options will be reasonable, and consider ventilation and daylighting measures.

This article describes the structure of a general machinery plant distribution system and protection system design.
Workshop equipment according to capacity and power factor, the calculation of the entire plant load, and so for reactive power compensation, short-circuit current calculation and the design of the main terminal. In order to ensure the safe operation of power plants should be installed in the power system relay protection devices, lines and transformers are divided into two parts, including over-current, overload, speed off and gas protection. Variable distribution surge arresters used for lightning protection, around the grounding grid should be public.
Distribution by changing the layout should include the high-low-voltage power distribution room, transformer room, office and lounge, layout program should be based on equipment type, capacity and connection options round into a rational distribution, and to consider measures for ventilation and lighting.
