本考案はガス湯沸器や暖房機等の燃焼制御装置
に関するものである。[Detailed Description of the Invention] The present invention relates to a combustion control device for gas water heaters, heaters, etc.

てある。 Conventionally, this type of combustion control device has been equipped with a lightning arrester, the configuration of which is shown in FIG. 1 is AC power supply,
2 is a zinc oxide varistor used as a lightning arrester.
It is connected between power lines L1 and L2. Reference numeral 3 denotes a combustion control circuit, which has an electrode 4 that is inserted into a combustion flame and detects the presence or absence of combustion flame, and which requires a ground wire. A zinc oxide varistor 5 is connected for lightning surge absorption.

る。 According to this configuration, the lightning surge superimposed between the power supply lines L1 and L2 is absorbed by the zinc oxide varistor 2, the influence on the combustion control circuit 3 is very small, and the lightning surge is superimposed between the power supply line L2 and the ground line. Lightning surges are also absorbed by the zinc oxide varistor 5.

る。 However, this type of combustion control device must be provided with an earth leakage interrupting device in addition to the lightning arrester described above. However, if a lightning surge occurs between the power lines L1 and L2 or between the ground and the ground, the currents flowing in the power lines L1 and L2 on the input side of the lightning arrester will momentarily become unbalanced, and a ground leakage interrupter will be installed. and the above unbalance time is the operating time of the earth leakage breaker (in the case of high-speed type)
Even if the current value is extremely short (within 0.1 seconds), the current value will be several hundred to several thousand A, resulting in residual magnetic flux, which may cause the earth leakage interrupter to malfunction.

る。 The AC power source 1, zinc oxide varistor 2, combustion control circuit 3, and electrode 4 are the same as those in the conventional example shown in FIG. A zinc oxide varistor 6 for absorbing lightning surge between the grounding wire is connected between the power line L2 connected to the zinc oxide varistor 2 and the grounding wire, and relay contacts 7 are provided on the power lines L1 and L2 on the output side.
Power lines L1, L on the output side from the relay contact 7
A zero-phase current transformer (hereinafter referred to as ZCT) 8 is disposed at 2, and an earth leakage relay 9 is provided which operates by the electromotive force generated in this ZCT 8 to open the relay contact 7. The ZCT 8 and the earth leakage relay 9 constitute an earth leakage interrupting device 10.

である。 According to this configuration, the power lines L1, L2
Even if a lightning surge occurs between the ground wire or the ground wire, this lightning surge will be absorbed by the zinc oxide varistors 2 and 6 installed on the input side of the ZCT8, and the output side will be affected by both varistors 2 and 6. Power line L1, L2
Since no current imbalance occurs in the ZCT 8, no electromotive force is generated in the ZCT 8, and therefore the earth leakage interrupter 10 does not malfunction due to a lightning surge.

る。 As mentioned above, the present invention connects a zinc oxide varistor between the power lines on the input side of the combustion control circuit and between the power line and the ground line, and also leaks electricity from the power line to which both zinc oxide varistors are connected to the output side. Since it is equipped with a zero-phase current transformer as a disconnection device, it is safe against lightning surges and leakage, and it is possible to provide a safe and reliable combustion control device that does not malfunction due to lightning surges. It can be done.
