Introduction

product details

First, an overview

VSL ZN63 -12kV series indoor medium pressure sealing type vacuum circuit breaker is developed by the company, the development of a new generation of vacuum circuit breaker, vacuum circuit breaker is in the air for insulation of indoor switch for AC 50Hz, rated voltage of 12kV and grid below plays the role of control and protection, vacuum circuit breaker in the frequent operation and needs breaking short circuit current situation has very excellent performance, fully meet the requirements of automatic reclosing and has high operating reliability and service life.

Circuit breaker in the switch cabinet in the form of installation can be fixed, can also be installed in the hand car.

The product can be installed in kyn28, KYN96 type switch cabinet or supporting other armoured metalclad withdraw switchgear: provide the rated current for 630A1600A, fixed sealed pole of vacuum circuit breaker can be installed on the 650mm, 800mm, width of the cabinet of the switch cabinet;

VSL (ZN63) -12kV vacuum circuit breakers are in compliance with CB, IEC and DL standards and specifications; GB/T11022, IEC60694 high voltage switchgear and control equipment standard common technical conditions; GBl984, DL403, JB3855 AC high voltage circuit breakers.

Two, the use of environmental conditions

1, ambient air temperature: upper limit of +40 degree, lower limit of -40;

2, altitude: less than 2000m (if the elevation, is rated insulation level increase);

3, wind pressure: no more than 700Pa (equivalent to the wind speed 34m/s);

4, seismic intensity: no more than 8 degrees;

5, pollution level: grade iv;

6, the maximum daily temperature difference: no more than 25 degrees;

7, relative humidity: daily average of not more than 95%, the average of not more than 90%;

8, non flammable, explosive hazards, chemical corrosion and violent vibration of the place.

I notice five.

1, circuit breaker name, type and order quantity;

2, circuit breaker rated current and rated short circuit breaking current;

3, the operating mechanism of the type, name, operating voltage and release type;

4, running cars and other spare parts, the number of spare parts;

5, if the user has other special requirements, when ordering negotiation.
