Problems solved by technology

[0004] The automatic sprinkler system includes an automatic spray pump. The power of the automatic spray pump is generally relatively large. It is easy to trip the open circuit breaker of the drawer cabinet in the power distribution room after starting for more than ten seconds. The solution is to replace the line to other power distribution rooms, the cost of this method is too high

Embodiment Construction

[0012] The present invention will be further described below in conjunction with specific embodiments.

[0013] The embodiment of the present application provides a method for solving the jump-starting trip of a high-power motor, and the method for solving the jump-starting trip of a high-power motor includes the following steps:

[0014] Close the water outlet valve of the spray pump to 1 / 3 state; follow the (Formula: multiply the square root of the capacity by 2, and add 4 units of seconds to the product) to adjust the time of the time relay when the star operation switches to the triangle operation in the motor. The capacity in the formula is a common name for power.

[0015] The purpose of closing the water outlet valve of the spray pump to 1 / 3 is to reduce the load. formula The T in it represents the time, and P is the power of the motor in the spray pump.

[0016] The time of the time relay is positively related to the power of the motor.

[0017] For example, the...

Abstract

The invention discloses a method for starting override trip of a high-power motor, which relates to the field of fire fighting and comprises the following steps of: closing a water outlet valve of a spray pump to a 1 / 3 state; and switching the time of the time relay during the triangular operation according to the star-shaped operation in the motor. According to the invention, only the water outlet valve of the spray pump needs to be closed to a 1 / 3 state, then the time of the time relay is adjusted according to a formula when the star-shaped operation is switched to the triangular operation in the spray pump motor, and the problem of override tripping of the start of the spray pump motor can be solved without any cost.

Description

technical field [0001] The invention relates to the field of firefighting, in particular to a method for solving the problem of high-power motor startup leapfrog tripping. Background technique [0002] Fire hydrant, officially called fire hydrant, is a fixed fire-fighting facility whose main function is to control combustibles, isolate combustion-supporting substances, and eliminate ignition sources. Indoor fire hydrants and outdoor fire hydrants. [0003] Fire protection systems include outdoor fire hydrant systems, indoor fire hydrant systems and fire extinguisher systems, and some also have automatic sprinkler systems. The fire hydrant is mainly used for fire trucks to take water from the municipal water supply pipe network or the outdoor fire water supply pipe network to put out the fire. Therefore, the indoor and outdoor fire hydrant system is also one of the important fire-fighting facilities for fighting fires. [0004] The automatic sprinkler system includes an au...
