Notes:

1. When the altitude is over 2000m, special explanation is required when ordering.

2. When the ambient temperature is lower than-25C, special explanation is required when ordering.

3. This size does not include pt installation space
4. The height of secondary chamber is included in such size. Th height can be adjusted according to the form of secondary chamber.

 

Spring Vacuum Circuit Breaker

• Solid sealed pole, more compact structure and higher reliability
• With the modular assembly structure, the cir cuit breaker can be maintained and replace d wit hou removing the entire cubicle
• The earthing function can be achiev ed with the coordination of three-position switch, which ensures more reliable closing capability
• The solid sealed pole of the vacuum circuit breaker is placed in the gas-filling tank, which is independent from the outside conditions
• Spring circuit breaker operating me ch anism enables manual electric operation with aut omatic reclosing function.

Three-position Switch

• There are three working positions of direct-actingthree-position switch: 1. Closing; 2. Opening; 3. Earthing
• The isolating and earthing operating holes are independent from each other, which avoids maloperation.
• Manual / motor opeation
• Operating mechanism has multiple automatic protection function for three-positi on switch, placed in the gas-filling tank, is independent of the outside conditions.

Potential transformer
Semi-insulated, fully sealed single-phase potential transformer with optional protection fuses and three-phase four-wire st ar connection type
It can be set on the top and back of the incoming line switchgear line switchgear, or it can be set into a pt cubicle realizing the measurement and acquisition of the voltage of the incoming and out going lines and busbar, and meeting the accuracy requirement of the measurement, metering and protection.
The connection between bushing in the gas tank and PT(optional): cable connection or direct plug-in type.

Fully insulated, fully sealed current transformer with multiple structural types such as ring-core typ open type, three-phase type and racetrack type, etc.
According to the current capacity and cable diameter, it can be set directly on the cable, in the cable chamber or on the cubicle across the tubular busbar, which can realize the measurement and acquisition of the current of the line and busbar and meet the accuracy requirements of the measurement. metering and protection.
Secondary winding has multiple sets of transformation ratio.

Secondary Chamber
with easy and quick installation all kinds of protection, control, me asurement and monito ring devices ca n be configured to cater for customers' needs The secondary chamber and the high voltage part are in dependent with each other, which ensures the operator's safety.
Pluc-in small bus and dismountable secondary chamber.

 

Density Type Barometer
The conditions of the gas pressure in side of the switchgear can be observed directly.
The temperature compensation sensor is equipped to display the pressure which is free from outside temperature influence
The en closed system is equipped to display the absolute pressure, which is free from the altitude influence.

The double-alarm electric node, smart terminal and background system are equipped for on-line monitoring.
