OVERHEAD TRANSFORMER CONNECTIONS
OVERHEAD TRANSFORMER CONNECTIONS The distance between the wire of distributing line and pole or framework: at least 0.3m per 10kV and 0.1m per 0.4kV. The net distance between lead wire, downlead in each phase and the lead wire or downlead of next phase: at least 0.3m per 10kV and 0.1m per 0.4kV. The lapping zone of distributing line's downlead and overhead insulated line should be connected in T type clamp or insulating parallel groove and covered in insulating materials. Besides, use waterproof tape and self-adhesive insulating tape, corresponding to the voltage classes, in the joint of insulating wine and insulating ...
OVERVIEW OF VARIOUS CLASSIFICATIONS OF 10KV TRANSFORMERS
TRANSFORMER OVERVIEW The 10 kv transformer is referred to as "distribution". It refers to a kind of static electric appliance in the distribution system that converts AC voltage and current according to the law of electromagnetic induction and transmits AC electric energy. A 10kV transformer is usually a power transformer that operates in the distribution network with a voltage rating of 10-35kV (mostly 10kV and below) and a capacity of 6300KVA and below directly to the end user. SORTED BY INSTALLATION LOCATION The transformer 10kv is divided into indoor and outdoor depending on the installation location. Outdoor installation is divided ...
ON LOAD TRANSFORMER
ON load transformer The transformer has impedance and will produce voltage drop during power transmission, which will change with the change of user side load. The fluctuation of system voltage plus the change of user side load will cause the great variation of voltage. On the premise of achieving local balance of reactive power, when the voltage changes beyond a fixed value, the on load transformer will operate after a certain delay to adjust the voltage and keep the voltage stable. The task of the power supply transformer is to supply power directly to the load center, and the primary ...
OPERATION AND MAINTENANCE OF BOX SUBSTATION
Ⅰ. BASIC REQUIREMENTS FOR box type substation OPERATION Box type equipment should be placed in a relatively high place, but not in a low-lying place, lest rainwater enters the electrical substation boxand affects its operation. Leave a gap when pouring the concrete platform to facilitate the laying of cables. There must be two reliable connections between the box and the grounding grid. When the box-type substation is working, the ground wire and the neutral wire can share a grounding grid. The grounding grid is generally grounded at the four corners of the foundation and then connected to form a whole. No ...
