Description

The chamber national team of unilateral service - KSO-395 M.

The KSO395 M series one-sided service chamber, hereinafter referred to as the KSO chamber, and busbar bridges for them are designed to equip switchgears with voltage of 6 or 10 kV alternating current with a frequency of 50 Hz of systems with isolated neutral.

The well-known Single-service chamber Team CSR BPJCRU series, Certificate 9345, Н02 В13 / 00, 1997) consisting of welded metal Caracas from bent steel profiles, inside the chamber is flexible; primary circuit equipment is on, on the facade there are drives of main load-bearing knives-breakers of the type VNR-10 disconnectors type RVZ and grounding knives, access to the chamber is provided through a door on which there is a window for viewing the inner zone, the door is locked with a key lock.

Known Chamber one-way service team series KSO - 390-P (RU, Certificate 11403, Н02 В1 / 26, 1998) containing; the frame is welded from bent steel profiles, the equipment of primary circuits, load breakers is placed inside the chamber, on the facade is a drive of load breakers , access to the camera is provided through the door, which is closed

IPC: Н02В 11/26.

a lock with a key, at the top of the chamber along the facade there is a box open from the sides, in which the secondary circuits are laid, a load switch with a lateral spring drive is installed in the chamber.

The purpose of this utility model is to significantly reduce the size of the camera while maintaining all the electrical characteristics of similar cameras, as well as improving the design.

This is achieved by the location of the busbars inside the chamber, as a result of which the maintenance of the chamber becomes more secure. This is also achieved by arranging an autogas three-pole load switch with a built-in manual spring drive for multiple switching operations inside the chamber.

The load switch is designed for switching under load of three-phase current circuits with a frequency of 50-60 Hz with a rated voltage of 3 to 10 kV and a rated current of 630 A with a grounded or insulated neutral.

The camera is a metal structure made of sheet bent profiles interconnected by mechanical riveting, as a result of which the production of cameras becomes more environmentally friendly.

locks:

1) a lock that does not allow the inclusion of grounding knives with the main knives of the load switch or disconnector turned on;

2) a lock that does not allow the inclusion of the main knives when the grounding knives of the load switch or disconnector are turned on;

3) a lock that prevents the door of the KSO chamber from opening with a VNPR installed with the VNPR main knives turned on;

4) a lock, which provides for the impossibility of opening the chamber door without disconnecting the VNPR load switch and inserting the inventory partition between the main VNPR contacts.

The KSO-395M camera consists of the following prefabricated elements: the right (1) and left (2) (Fig. 1) side panels; in the upper part of the chamber there are busbars (3) (Fig. 2) and a VNPR load switch (4) (Fig. 2). At the bottom of the chamber is a grounding knife (5) (Fig. 2) and, if necessary, transformers and arresters. In the upper part and on the rear wall there are safety valves (6) (Fig. 1). VNPR and grounding knives are controlled by

leads (7 and 8) (Fig. 2) located on the front panel of the CSR camera. In the chamber door (9) (Fig. 1) there is a viewing window (10) (Fig. 1) for an overview of the position of the switch (on / off).

The camera works as follows: when receiving power from the input cable, switching is performed using the VNR of the outgoing power line.

Claims (1)

The KSO-395M camera, containing a high-voltage switch, current transformers and disconnectors, characterized in that it is made in the form of a metal structure from bent sheet profiles interconnected by means of riveting, has significantly smaller dimensions than similar cameras, while maintaining all electrical characteristics, moreover inside it there are busbars and an autogas three-pole load switch with an integrated manual clamping drive for multiple switching operations under load of three-phase current circuits earthed or isolated neutral.
