[0002] Five-hole differential quick die closing is a power system protection device used to protect equipment such as transformers and busbars in the power grid. When a fault occurs in the system, the five-hole differential protection can detect the current difference, accurately judge the fault location, and thus quickly cut off the faulty device to prevent the fault from expanding and ensure the safe and stable operation of the power grid. The auxiliary ejection integrated block is a device in the power system, usually used together with the differential protection device to enhance the performance of the differential protection. The auxiliary ejection integrated block can increase the speed and sensitivity of the differential protection, help detect faults faster and cut off the faulty equipment, and improve the safety and reliability of the power grid.

A first avoidance position is opened at the top of the quick die closing integrated block. A second avoidance position is opened on one side of the outer wall of the quick die closing integrated block. An integrated block installation hole is opened on the front surface of the auxiliary ejection integrated block.

[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model in conjunction with the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0024] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0025] Embodiment 1, as Figures 1-6 shown, the present utility model provides an integrated block of a five-hole differential quick mold clamping and auxiliary ejection integrated block, including an auxiliary ejection integrated block 1. One side of the outer wall of the auxiliary ejection integrated block 1 is fixedly installed with a quick mold clamping integrated block 2. Five servo valve mounting holes 3 are opened on the front surface of the quick mold clamping integrated block 2. A proportional valve mounting hole 4 is opened on the front surface of the quick mold clamping integrated block 2. A first safety overflow valve 5 is opened at the bottom of the quick mold clamping integrated block 2. A second safety overflow valve 6 is opened on one side of the outer wall of the quick mold clamping integrated block 2. A first avoidance position 7 is opened at the top of the quick mold clamping integrated block 2. A second avoidance position 8 is opened on one side of the outer wall of the quick mold clamping integrated block 2. An integrated block mounting hole 9 is opened on the front surface of the auxiliary ejection integrated block 1.

[0026] The effects achieved by the entire Embodiment 1 are as follows. The five servo valve mounting holes 3 refer to the mounting holes of the five-hole differential servo integrated block. The proportional valve mounting hole 4 refers to the mounting hole of the NG10 electro-hydraulic proportional valve. The first safety overflow valve 5 and the second safety overflow valve 6 both refer to the quick mold-closing safety overflow valves. The first mounting port 15 and the second mounting port 16 both refer to the mounting ports of the NG10 electro-hydraulic directional valve. Then, it is combined and integrated with the five-hole differential quick mold-closing and auxiliary ejection integrated block 1. The integrated block is forged from 45# steel or machined from precision nodular iron. Five quick mold-closing servo valve mounting holes 3 are machined on the quick mold-closing integrated block, as well as the connection holes with the quick mold-closing oil cylinder and the relevant hole positions integrally connected with the auxiliary ejection integrated block 1. An installation hole for installing the electro-hydraulic directional valve of the auxiliary ejection oil cylinder is opened on the auxiliary ejection oil cylinder. There is an annular sealing ring 11 on the connection surface with the five-hole differential quick mold-closing, as well as the incoming oil P and T holes of the main oil circuit and some pilot oil ports. The valve body is blackened. After overall installation and testing, there shall be no oil leakage under the oil pressure of 250 bar. The pressure oil ensures the stability of direct-pressure mold-closing and mold-opening due to the system pressure, thereby improving the working efficiency and further enhancing the usage effect of the combined integrated block of the five-hole differential quick mold-closing and auxiliary ejection integrated block 1.

[0027] Embodiment 2, as Figures 2-6 shown, a combined sealing position 10 is provided on one side of the outer wall of the auxiliary ejection integrated block 1. An annular sealing ring 11 is fixedly installed on the back surface of the quick mold-closing integrated block 2. A quick mold-closing port 12 is opened on the back surface of the quick mold-closing integrated block 2. A main ejection port 13 is opened on the back surface of the quick mold-closing integrated block 2. A plurality of connecting screw holes 14 are opened on the back surface of the quick mold-closing integrated block 2. A first mounting port 15 is opened on the front surface of the auxiliary ejection integrated block 1. A second mounting port 16 is opened on the front surface of the auxiliary ejection integrated block 1.

[0028] The effects achieved by the entire Embodiment 2 are as follows. The oil port for ejection is designed as the standard NG10 proportional valve mounting hole 4. A connection surface with the auxiliary ejection integrated block 1 is opened on the side of the valve. The main oil circuit P and T holes connected with the auxiliary ejection are opened on this connection surface. The connected auxiliary ejection also has an installation hole surface combined sealing position 10, that is, an oval and square sealing ring surface. The double sealing of the periphery and the oil port ensures the effective sealing performance between the valve plates. Secondly, a first mounting port 15 and a second mounting port 16 are opened on the auxiliary ejection integrated block 1, that is, two groups of mounting ports of the NG10 electro-hydraulic directional valve, which drives the action of the auxiliary ejection oil cylinder, ensures the sealing performance during the work between the two integrated blocks, guarantees the quality, and further improves the usage effect of the combined integrated block of the five-hole differential quick mold-closing and auxiliary ejection integrated block 1.

[0029] Working principle: The five-orifice differential rapid mold-closing and auxiliary ejection integrated block 1 combined integrated block utilizes the combination of two integrated blocks to achieve differential rapid mold-closing ejection and auxiliary ejection functions, making the oil circuit compact and minimizing the pressure and flow losses in the system. The five oil ports opened on the five-orifice rapid mold-closing integrated block are special holes for installing the five-orifice differential mold-closing servo valve, namely the five servo valve mounting holes 3, which are specially customized holes according to the designer's requirements. The oil ports used for the rapid mold-closing integrated block 2 are standard NG10 proportional valve oil ports. A connection surface is provided on the side of the proportional valve, and main oil passage P holes and T holes connected to the auxiliary ejection are opened on this connection surface. Then, the connected auxiliary ejection also has oval and square sealing ring surfaces. Through the action of the combined seal position 10 and the annular seal ring 11 provided at the rapid mold-closing port 12, double sealing of the periphery and the oil ports is ensured, effectively ensuring the sealing performance between the valve plates, improving the working quality and efficiency, and thus enhancing the usage effect of the five-orifice differential rapid mold-closing and auxiliary ejection integrated block 1 combined integrated block.
