Detailed Description
The present utility model will be further described in detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent.
An embodiment of a multi-gun ac charging stake:
as shown in fig. 1, the utility model adopts a connection mode of one pile with multiple guns, and can configure different numbers of charging guns according to the requirements of the site, the number of the charging guns is supported to be 1-20, the charging pile comprises a plastic shell breaker QF1 with a leakage function, a three-phase electric energy metering ammeter PJ1, miniature breakers Q1-Qn, phase change switches K1-Kn, charging gun management modules P1-Pn and charging guns C1-Cn, wherein the miniature breakers, the phase change switches and the charging gun management modules are the same as the number of the charging guns.
In the embodiment, 1 molded case circuit breaker QF1 with a leakage function is adopted as a main inlet switch, three-phase electric energy meters are configured on the outlet side of the inlet main switch, charging guns C1 to Cn connected with the three-phase main inlet in parallel are adopted as protection switches, phase change switches K1 to Kn are arranged between the charging guns C1 to Cn and the three-phase main inlet, the phase change switches K1 to Kn are positioned at the outlet ends of the miniature circuit breakers Q1 to Qn and the inlet ends of the charging guns C1 to Cn, and P1 to Pn are each charging gun management module for controlling CP signal output, temperature detection, gun state detection and voltage current detection of the charging guns.
The utility model provides a multi-gun alternating-current charging pile, which can manually select one phase line of three phases to charge a charging gun according to requirements, for example, when three phases are unbalanced, a high-load phase line load is transferred to a low-load phase line, the unbalanced degree of the three phases is improved, or when one phase line fails or other reasons cannot continue to be used, the load on the phase line is transferred to other phase lines which can be normally used.
As other embodiments, as shown in fig. 2, a charging pile controller M1 may be further provided, and the charging pile controller is connected with a three-phase electric energy meter to obtain the three-phase unbalance degree, and the automatic adjustment of the three-phase load condition is realized through a phase change switch and/or a charging barrel management module connected with the charging pile controller. For example, the charging pile controller collects three-phase power, voltage and current data of the three-phase electric energy meter, and when the three-phase unbalance exceeds an allowable value, the three-phase unbalance is reduced by controlling the PWM output duty ratio of the charging gun controllers P1-Pn and performing phase change operation on the phase change switches K1-Kn.
When three phases are unbalanced, the specific process of automatically adjusting the three-phase load condition is as follows:
when the output three-phase unbalance exceeds a first threshold value and is smaller than a second threshold value, the charging controller M1 sends an adjusting instruction through the CAN bus, reduces the output power of a phase line with larger load, and reduces the power requirement of the vehicle-mounted charger of the electric automobile by reducing the PWM output duty ratio of the P1-Pn module, so that the aim of three-phase balance is fulfilled. When the output three-phase unbalance exceeds a second threshold, the output PWM duty ratio cannot reach the aim of three-phase unbalance adjustment, at the moment, the charge controller transfers the load of the high-load phase line to the low-load phase line through the phase change switches K1-Kn, so that the three-phase unbalance is below the second threshold, and still exceeds the first threshold after being adjusted through the phase change switches K1-Kn, and at the moment, the target value of three-phase balance is reached by reducing the PWM output duty ratio of the P1-Pn module.
The charging controller can read the maximum power of the current equipment through the three-phase electric energy meter PJ1, and can control the output power of each charging gun at the same time, so that the output power of the whole machine can be controlled to be not more than the set maximum value, the set maximum value can be set locally or remotely, and the risk of overload operation of the transformer in the transformer area can be avoided through the function.
