Description

本発明は、移動用発電装置に係り、特に移動電源車用のユニット構造に関するものである。   The present invention relates to a mobile power generator, and more particularly to a unit structure for a mobile power supply vehicle.

商用配電線路の一部区間で停電工事等を行う場合において、停電工事区間以降の負荷に電力を供給するために移動用発電装置を設置し、商用電源側からこの移動用発電装置側に無停電にて電力を切換えて負荷側に供給している。
従来、この無停電切換装置としては、特許文献１のようなものが公知となっている。 When a power outage work is performed in a section of the commercial distribution line, a mobile power generator is installed to supply power to the load after the power outage work section, and there is no power outage from the commercial power supply side to the mobile power generator side. The power is switched at and supplied to the load side.
Conventionally, as this uninterruptible switching device, the thing like patent document 1 is publicly known.

この特許文献には、配電線の区分開閉器よりも電源側に非接触電圧センサ及び非接触電圧・電流センサを設け、また、区分開閉器よりも負荷側に非接触電圧・電流センサを設ける。そして、区分開閉器の近くに無線式同期検定器を配置して電源側に非接触電圧センサの出力と負荷側非接触電圧センサの出力に基づき、電源側と負荷側との電圧検相を行い、その結果を無線で移動用発電装置に送信することが記載されている。
特開２００１−１２８３６３号公報 In this patent document, a non-contact voltage sensor and a non-contact voltage / current sensor are provided on the power supply side of the distribution switch of the distribution line, and a non-contact voltage / current sensor is provided on the load side of the classification switch. A wireless synchronous tester is placed near the section switch and voltage phase detection is performed on the power supply side and load side based on the output of the non-contact voltage sensor on the power source side and the output of the load-side non-contact voltage sensor. The result is transmitted wirelessly to the mobile power generator.
JP 2001-128363 A

特許文献１で示す無停電で電源を切換える方法では、無線式同期検定器は、区分開閉器の配設された電柱に取り付けられ、センサによって検出された信号を移動電源車に伝送し、送信された位相信号を基に移動用発電装置側では自動位相追従制御を行ない、配電線と移動用発電装置の位相や周波数、電圧値などが所定誤差範囲内に入った時、移動用発電装の遮断器を投入している。   In the method of switching the power supply without uninterruptible power shown in Patent Document 1, the wireless synchronous tester is attached to a power pole provided with a section switch, transmits a signal detected by a sensor to a mobile power supply vehicle, and is transmitted. The mobile power generator side performs automatic phase tracking control based on the phase signal, and shuts off the mobile power generator when the phase, frequency, voltage value, etc. of the distribution line and the mobile power generator are within the specified error range. The vessel is turned on.

移動用発電装置にはエンジンや発電機、及び制御盤等が搭載されており、限られたスペースの中に各機器や部材が配置されている。その上、近年の移動用発電装は、特許文献１で見られるように無線通信装置等が搭載されるようになっており、ますます部品点数が多くなっているにも拘わらず機器の性能や機能のみを追求し、各機器を移動用発電装置に搭載する場合には空いているスペースに単に配置することで、停電工事前後の機器の積み込みや積み下ろし等を考慮した特に移動用発電装置全体としての一貫性に欠けている。したがって、各機器を車両に搭載する際には非常に作業性が悪く、場合によっては車両内部にまで入り込んで機器を持ち運ぶ必要が生じ、装置としての使い勝手等が一切考慮されていないため使用上の不備が生じている。   The power generator for movement is equipped with an engine, a generator, a control panel, and the like, and each device and member are arranged in a limited space. Moreover, recent mobile power generation devices are equipped with wireless communication devices and the like, as seen in Patent Document 1, and although the number of parts is increasing, When pursuing only the functions and mounting each device on a mobile power generator, simply placing it in an open space, especially considering the loading and unloading of the equipment before and after a power outage, as a whole mobile power generator Lack of consistency. Therefore, when each device is mounted on the vehicle, the workability is very poor, and in some cases, it is necessary to carry the device by getting into the vehicle, and the usability as a device is not considered at all. There are deficiencies.

また、同期検定部や無線装置等の機器への電源としては、それぞれ専用の充電ケーブルにより電源を供給しているため、それぞれ機器固有の接続方法が採れている。図５、図６は従来用いられている移動用発電機車側と各機器側とを接続するケーブルを示したもので、一般には同期検定部や無線装置等の各機器は別々の製品として製作されてメーカが異なることにより、そのコネクタ構造は同図Ａ、Ｂ、Ｃで示すようにそれぞれ異なり、例えば３種類の充電用ケーブルが必要となる。また、各機器で電源装置が異なることでそれぞれ専用の充電器が必要となり、機器コスト、メンテナンス性が悪化すると共に、各機器への電源供給用のケーブルが必要となり、該当するケーブルをいちいち探す必要が生じるなどの問題を有している。   In addition, as a power source for devices such as a synchronization verification unit and a wireless device, since power is supplied by a dedicated charging cable, a connection method specific to each device is adopted. FIGS. 5 and 6 show the cables used to connect the mobile generator car side and each device side that have been used in the past. Generally, each device such as a synchronization verification unit and a radio device is manufactured as a separate product. Depending on the manufacturer, the connector structure is different as shown in FIGS. A, B, and C. For example, three types of charging cables are required. In addition, since each device has a different power supply, a dedicated charger is required, which reduces device costs and maintainability, and requires a power supply cable for each device. Have problems such as
