摘要： PROBLEM TO BE SOLVED: To enable a customer to enjoy the discount service of an electricity bill according as a substation for distribution is newly installed. SOLUTION: This electricity bill calculation system includes: a current gross loss electric energy calculation part for calculating a current gross loss electric energy within the feeding range of a first substation for distribution; a current gross loss costs calculation part for calculating current gross loss costs corresponding to the current gross loss electric energy; a new gross loss electric energy calculation part for calculating new gross loss electric energy within each feeding range of first and second substations for distribution; a new gross loss cost calculation part for calculating new gross loss costs corresponding to the addition result of the new gross loss electric energy; a discount service financial funds calculation part for calculating discount service financial funds by subtracting new gross loss costs from the current gross loss costs; and an electricity bill calculation part for calculating an electricity bill for a discount service target customer by distributing the discount service financial funds to every discount service target customer.

摘要： PROBLEM TO BE SOLVED: To provide a distribution board installing instrument, which is suitable for certainly and easily installing a newly-installed distribution board at an installation place in an intermediate part in a row of existing distribution boards. SOLUTION: A distribution board installing instrument includes a pair of instrument body portions which has jaw-shaped hook portions capable of being hooked to folded portions formed so as to project to a distribution board case back surface both side edges, at both ends in a longitudinal direction, and extending/contracting in the longitudinal direction to change the total length thereof; engaging portions capable of being engaged with portions to be engaged which is provided in intermediate areas of each pair of the instrument body portions; and driving portions for transmitting driving force by engaging those, and capable of adjusting the total length of those by synchronously expanding/contracting the instrument body portions. The pair of instrument body portions may have various shapes according to the presence/absence or layout of the folded portion on a back surface of an existing distribution board, and a relationship between the layout of the existing distribution board and an installation place of a newly-installed distribution board, and the like. The pair of the instrument body portions can be combined with a predetermined reinforcing member. COPYRIGHT: (C)2013,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a disconnection protective relay capable of solving the hot-line state of a disconnection section by opening a breaker by accurately detecting a single-line disconnection with no ground fault. SOLUTION: The disconnection protective relay has an input conversion section 11 inputting the current and voltage of its own terminal, a transmission-reception section 12 transmitting and receiving current data and a current arithmetic section 13 deciding the presence of an operation on the basis of a predetermined setting condition from the current data of its own terminal and an opposite terminal. The disconnection protective relay further has an operation-circuit decision section 18 inputting the open-close state of the breaker fitted to a transmission distribution line and deciding a single-line operation state or a two-line operation state and a differential-current arithmetic section 14 deciding the presence of the operation on the basis of the predetermined setting condition from the differential current of each phase of its own terminal and the opposite terminal. The disconnection protective relay further has an accident detecting section 16 detecting an undervoltage and a ground-fault overvoltage by the voltage data of its own terminal and an operation deciding section 15 outputting a disconnection detecting signal according to a condition detecting no accident by the accident detecting section 16, a condition having no differential current in the differential-current arithmetic section 14 or a condition having no disconnection in other phases.
