However, today, when the number of electric appliances and computer equipment has increased, the following problems have occurred, and users have suffered great losses. (A) Malfunction of computer equipment etc. due to electrical noise: Power lines for supplying power and weak wires for providing information are mixed in a narrow building space, and noise is induced in the weak wires. In some cases. In addition, lightning can hit buildings directly, or lightning surges can enter the tracks and destroy light electricity and communication equipment. Filters and protectors are not enough to protect equipment from these obstacles and ultimately require grounding. (B) Necessity of installation work: Most light electrical appliances require type 3 grounding, but the use of outlets with grounding electrodes is still insufficient. To actually perform the grounding work, an electrician is arranged and the work is performed using the ground wire and the ground electrode, which is expensive. Therefore, the grounding work is actually avoided. Therefore, the malfunction of the weak electrical equipment which is considered to be caused by noise is left unchecked. (C) Malfunction of computer equipment due to voltage fluctuation: Computer-related equipment imported from abroad to Japan often has a voltage specification of 110 to 120 V, and malfunctions when there is a voltage drop or voltage fluctuation. . In addition, when the voltage is low, adverse effects such as a long cooking time in a microwave oven and a shortened life of an electric lamp such as a fluorescent lamp have occurred. (D) Need for power saving: In some regions, the voltage received from the power company is high, and some use more energy than necessary. Therefore, power can be saved by selecting loads such as refrigerators, air conditioners, and hot carpets, adjusting the voltage to the rated voltage, and using power.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A normal 100 V outlet is
The transformer is connected to the secondary side of the pole transformer of the power company and the transformer of the private substation, and the transformer is to be subjected to the second kind of grounding work according to the technical standards of electrical equipment.
Therefore, since one side of the outlet of the outlet is always grounded, the same applies to an outlet with an extension cord for grounding an electric device at a location away from the outlet. So, like the recent wall-mounted grounded outlet,
The feature is that the ground electrode terminal is also provided to the outlet with the extension cord. Although the outlet voltage is nominally 100 V, there are many fluctuation factors due to fluctuations in the supply voltage from the electric power company, voltage drops due to being away from private substations, and particularly in equipment imported from overseas. If the rated voltage of the specification is 110 to 120 V, malfunction occurs in Japan. Therefore, a feature is that a transformer having a variable tap is built in an outlet with an extension cord so that an arbitrary voltage can be obtained. The voltage, current, and the like of the outlet with the extension cord are checked with a built-in meter, but when used as a power saving device, a predetermined effect can be obtained by lowering the voltage.

Embodiments of the present invention will be described below with reference to the drawings. Figure 1 shows the grounding terminal (3) on the outlet with extension cord
Is given. A determination is made as to whether a current is flowing to the power supply by turning on the LED (4) and a determination on the ground side. Most of the electrical equipment is a third-class ground (100Ω or less), so if it is connected to the ground terminal (3), grounding can be performed without electrical work. FIG. 2 shows a transformer built in an outlet with an extension cord. While monitoring the voltmeter (6), the voltage can be adjusted by the tap changeover switch (5) to obtain an arbitrary voltage. If the built-in transformer is used for lightning surge countermeasures, it is possible to prevent computer board circuit burnout due to lightning surge that often occurs at the time of lightning strike. In addition, a built-in buzzer (7) that detects an overcurrent (the extension cord has a rated current of 15A) in advance and issues an alarm will prevent the breaker from operating suddenly and causing a loss to the load's computer circuit. Can be prevented.
