Description
The complete distributing device of a series of km-7m of 10 (6) kV on currents 630-3150 and
Complete distributing devices of the KM-7M, KM-7MK series of 10 (6) kV, on currents (630-3150) A, the industrial frequency of 50 Hz are intended for reception and distribution of electric energy on objects of power supply of the enterprises of all branches of a national economy and agricultural consumers. The complete and distributive KM-7M, KM-7MK series represent set of cases and compartments (further - CREWE), with switching devices of measurement, automatic equipment and for - boards, and also managements, alarm systems and other auxiliary devices connected among themselves according to an electric circuit. The KM-7M, KM-7MK series are intended to CREWE for internal installation and represent set of cases of a metal design, calculated on bilateral service. SERVICE CONDITIONS: Service conditions in accordance with GOST 15150 and GOST 15543: • climatic modification and category of placement: • for KM-7M,KM-7MK - the internal OUSE installation, • height above sea level to 1000 m; • relative humidity of air no more than 80%; • environment is inexplosive, not containing conducting dust and aggressive gases and vapors in the concentration destroying metals and isolation. The questionnaire coordinated between the customer and manufacturer forms the basis for the order of CREWE. The main technical characteristics and parameters of CREWE correspond to the values specified in table 1.
FEATURE of CREWE KM-7MK Now, for the purpose of further increase of a technological level, reliability and quality of products, plant mastered production of chambers of cassette execution of the KM-7MK series. Chambers of the KM-7MK series have the increased reliability in operation due to application modern high-voltage kommu-tatsionny devices (vacuum switches) having a high mechanical and switching resource. Relay protection is provided with multipurpose, small-sized, highly reliable microprocessor blocks of such firms as AREVA(MiCOM), SIEMENS(Siprotec), ABB(REF,REX) and other famous producers. Use of the digital device of protection against arc short circuits, and also reliable blocking switching vysokovolt-ny devices protects service personnel from injuries and damages, minimizing or excepting destructions in cells and sections RU, reduces the expenses connected with violation of power supply of consumers thereby increasing operational safety. On the cartridge of chambers of the KM-7MK series as the switching equipment chatel of production of ABB, SIEMENS firms, Taurida electrician, etc. can be put high-voltage vacuum vyklyu-. The main advantages of these chambers is the following. All chambers in the distributing device have identical depth. They can be established closely to a wall and razmeshche-ny on the simple base. Access to a compartment of cable assembly of a high voltage can be provided in front and from below. Manual switchings do not demand considerable efforts. Wrong actions of personnel are prevented by means of system of the built-in blocking and padlocks. With switches, contactors, section disconnectors and transformers of tension pozvolya-yut this equipment in use is easy to serve and repair sliding elements. Full safety of operation of CREWE of the KM-7MK series is ensured by constructive decisions, simplicity and presentation of switching operations, and also the thought-over system of expeditious blocking. The special design of reciprocal parts of a cell allows to determine depth of an entrance of rozetochny contact to motionless part, not at - changing additional resources and measurements.
