Description

  TECHNICAL FIELD The present invention relates to a cable storage device for an electric charging type accident exploration device that is used when exploring an accident point of a distribution line using a high-voltage output cable and a ground cable in the event of a distribution line accident. .

  Conventionally, there is an accident point search method in which a high voltage is applied to an accidental power outage section of a high-voltage overhead distribution line whose power supply is stopped or disconnected, and the current flowing at that time is detected to search for a ground fault point (patent) References 1 to 3).

  For example, in the event of a distribution line accident, as shown in FIG. 9, a high-voltage output cable 100 and a ground cable connected to a portable box-shaped charging type accident investigation device P mounted in a car K 101 was used to search for an accident point on the distribution line.

  When the cables 100 and 101 of the electric charging type accident investigation device P are not in use, the cables 100 and 101 are removed from the electric charging type accident investigation device P and manually wound to an arbitrary size. It was common to place it on the type accident investigation device P.

Further, when both the cables 100 and 101 are used, it is necessary to pull out the cables 100 and 101 that are being wound out of the vehicle K.

  However, as a problem at the time of emergency work in the past, it takes time to pull out and wind up the cables 100 and 101, and the handling thereof is likely to be complicated, and there is a possibility that the cables 100 and 101 are damaged.

  Moreover, when pulling out the cables 100 and 101 from the inside of the car K, it is necessary to carefully draw out the cables 100 and 101 while correcting the hooks of the cables 100 and 101. However, the cables 100 and 101 are caused by kinks or the like already existing in the cables 100 and 101. There was also a risk of damage.

  Furthermore, since it takes time to install, withdraw, and move the electric charging type accident exploration device P, workers are irritated and frustrated in order to shorten the accident power outage time.

  Moreover, since the inside of the vehicle K becomes messy with the mixed cables 100 and 101, it becomes necessary to rewind the cables 100 and 101 that become messy after use. At this time, how to wind the cables 100 and 101 When there are individual differences in time, time, etc., and the winding place of the cables 100 and 101 is inappropriate, the worker feels tired.

  Further, the length of the cables 100 and 101 may include a distribution box for supply and a borrowed electric room that are the points for charging, installed in the user's premises, or charging in a shopping street or a downtown area. When there are many parked vehicles near the point, it is necessary to make the length of the cables 100 and 101 sufficiently long. The fatigue of the workers was even greater.

  Therefore, the present invention was created in view of the existing circumstances as described above, and realized an improvement in cable drawing efficiency and storage efficiency and an extension of the cable in the electric charging type accident investigation device. An object of the present invention is to provide a cable storage device for an accident investigation device.

  The cable storage device of the power-accident type accident investigation device according to the present invention includes a rotating drum for winding a cable, and a winding rotation provided with a handle for rotating the rotating drum via a timing belt for power transmission. Each of the plate and the earth reel provided with a handle for directly winding the earth cable is accommodated in the box, thereby solving the above-described problems.

  In addition, a high-voltage terminal and a grounding terminal are provided inside a recess formed on the side surface of the rotating drum, and the terminal is a rotary contact portion formed on a power supply side fixing plate that serves as a bearing portion of the rotating drum. The rotary contact portion is connected to the power cable of the power-applying device, thereby solving the same problem as described above.

  Further, the power supply side fixing plate is provided with a guide rail for slidably engaging a guide protrusion formed inside the recess, thereby solving the above-described problem.

  The cable storage device of the power-accident type accident investigation device according to the present invention includes a rotating drum for winding a cable, and a winding rotation provided with a handle for rotating the rotating drum via a timing belt for power transmission. Since each of the plate and the ground reel with a handle for directly winding the ground cable is housed in the box, the cable can be pulled out and wound in a short time during emergency work. The cable will not be damaged.

  In addition, the installation, removal, and movement of the electric charging type accident investigation device can be facilitated, and the accident power failure time can be shortened without causing the workers to get impatient or frustrated.

  Furthermore, since the interior of the vehicle is not messy with the mixed cable, there is no need to rewind the cable after use.

  In this connection, there is no individual difference in the winding method and time of the cable.

  In addition, since the cable winding location does not become inappropriate, the operator's feeling of fatigue can be reduced.

  In addition, when supply distribution boxes and leased electrical rooms that serve as points for charging are installed in the user's premises, or when there are many parked vehicles near the points for charging in shopping streets and shopping centers The length of the cable can be sufficiently ensured without burdening the operator.

  In addition, a high-voltage terminal is arranged inside a recess formed on the side surface of the rotating drum, and a grounding terminal is provided on the outside thereof. The terminal is formed on a power supply side fixing plate that becomes a bearing portion of the rotating drum. The rotary contact portion is slidably contacted with the rotary contact portion, and the rotary contact portion is connected to a power cable of the power application apparatus. As a result, even if the power charging device gets wet with water due to weather conditions, etc., even if water intrudes from the outside to the high voltage side inside, by the grounding terminal arranged on the outside, Since leakage to the outside of the apparatus can be prevented, electric shock of the measurer can be prevented.

  The power supply side fixing plate is provided with a guide rail for slidably engaging a guide protrusion formed inside the recess. Thereby, the rotating drum and the power supply side fixing plate are arranged at appropriate positions. In addition, the breakwater formed on the side of the rotating drum and the recess on the power supply side fixing plate prevent the intrusion of water into the internal high voltage area even when the device gets wet due to weather conditions. Play a role like Furthermore, the presence of these folds increases the creeping distance between the high voltage portion and the ground terminal portion, and therefore plays a role of preventing unnecessary leakage to the ground terminal.
