When preparing the above-described cross-linked polyolefin insulating composite pellet, if the organic peroxide is less than 1 part by weight, the cross-linking density of the insulating composite decreases, and if it exceeds 5 parts by weight, side reactions other than cross-linking increase.

The above-described charcoal powder is manufactured by pulverizing charcoal obtained by carbonizing bamboo, and the bamboo carbonized charcoal powder is known to exhibit an excellent deodorizing effect, and is effective in removing the odor of plastic extruded products by adding it to cooling water.

(Experimental Example 1)

In order to check the deodorizing power of the above-described bamboo carbonized charcoal powder, the deodorization rate was measured through a gas detection tube method applying ASTM D1988-06.

First, a rubber stopper was inserted into a 500 mL Erlenmeyer flask to allow sealing, and a hole was drilled to allow entry and exit of the detector tube. 1 µl of ammonia aqueous solution was injected into the flask to induce an odor. After 30 minutes of occurrence of odor, 1 mg of bamboo charcoal powder was injected, and residual gas was compared and analyzed using a gas detector every 30 minutes, 60 minutes, and 90 minutes. The experiment was conducted in a fume hood at 23°C, and a blank test was measured by injecting water. The results are shown in Table 3 below.

Deodorization rate (%) Blank Charcoal powder 30 minutes 12 50 60 minutes 15 53 90 minutes 19 57

As described above, it can be confirmed that the bamboo carbonized charcoal powder exhibits excellent deodorizing power, and the odor remaining in the plastic extrudate can be removed by using the bamboo carbonized charcoal powder as a cooling water additive.

According to the above configuration, the operation of the uninterruptible power supply device according to an embodiment of the present invention is as follows.

When commercial AC power is applied through the commercial power line 1, the low frequency is filtered by the EMC filter unit 31 and then rectified primarily by the rectifying unit 38.

Next, it is applied to the transformer 33 via the inrush current limiting unit 32.

In this way, the power applied to the transformer 33 is transformed by the transporter 33 and then secondaryly rectified and smoothed while passing through the rectification smoothing unit 36 and output as a direct current to the battery (not shown). Is saved.

In this case, the primary current sensing unit 347 of the driving unit 34 senses the current flowing through the primary side of the transformer 33 and inputs it to the driver U2, and the driver U2 corrects the power factor to be 1 The car feedback unit 344 is driven.

On the other hand, when an overvoltage of AC 325V or higher is input, the voltage divided by the resistors R1, R2, R3, R4, R9 of the overvoltage protection unit 38 conducts the regulator U1 and the transistor Q1 is turned on. By allowing the power supply (+V) of the auxiliary power supply unit 343 of the driving unit 34 to flow to the ground, the operating voltage of the driver U2 is forcibly lowered to a voltage below the inoperable state, thereby stopping the operation of the entire converter.

The Zener diode ZD1 of the overvoltage protection unit 38 prevents over-input, which may damage the transistor Q1.

If a voltage of less than AC 315V is input, the transistor Q1 of the overvoltage protection unit 37 is turned off, and the operating voltage of the driver U2 automatically returns to normal power, and the converter resumes operation. Is done. At this time, the resistors R5, R6, R7, and R8 of the overvoltage protection unit 37 and the regulator U1 supply a voltage for maintaining the turn-off state of the transistor Q1.

The capacitor C1 of the overvoltage protection unit 38 serves to adjust the interval between the protection operation time 325VAC and the automatic recovery time 315VAC of the transistor Q1.
